I, Toyo Kazu Yamada, started my research from 1998. When I was a Master student (1998-2000) I developed a Mott detector for visualizing surface magnetic domains by combining with SEM (scanning electron microscopy), which is so-called spin-polarized SEM (or SEMPA). During that time, Prof. Dr. Tadashi Mizoguchi and Dr. Jun Fujii were my supervisors (Gakushuin University, Tokyo). From 2000 till 2004, I was a PhD student of Radboud University Nijmegen (Prof. Dr. Herman van Kempen, The Netherlands) and Gakushuin University (Prof. Dr. Tadashi Mizoguchi, Japan): double degree program. I developed spin-polarized STM (scanning tunneling microscopy). Atomic-size magnetic domain structures of ultra thin layerwise antiferromagnetically coupled Mn films on Fe(001) were deeply studied at 300 K in UHV. During 2004-2008, after I got two PhD degrees, I got a JSPS research fellow (PD) position, and subsequently got an Assistant Professor position at Gakushuin University, where X-ray, AFM, VSM, Kerr, and many experimental setup treatments for education were learned. After the hard time due to too much education matter, I decided to go to Germany to join exciting researches. I was studying with Prof. Dr. Wulf Wulfhekel at Karlsruhe Institute of Technology (KIT) in 2008-2010 as a Humboldt research fellow. I have studied organic molecules by using spin-polarized STM and found that single phthalocyanine molecules can be the smallest magneto resistance sensor. Also, magneto electric coupling (bcc-fcc phase switching by electric field) was found on the surface of Fe nano islands on Cu(111). Further, high and low spin state in the spin crossover molecules was tuned by injecting electrons from the STM tip. In 2010, I got a Tenure-Track Associate Professor position at Chiba Univ. in Japan, and in 2015, I got the Tenure. Starting from 2010, in Chiba Univ., I opened my lab. So far (-2018), four home-built UHV-STM setups (three low temperatures and one room temperature) have been developed. Using these setups combined with spin-polarized STM techniques, now, we are studying single magnetic atoms, organic molecules, graphene nanoribbons, Fe/MgO interface, nano magnets on s-wave superconductor, and life molecules.

Science Advances 9(36) 2023年9月8日Superconductors are of type I or II depending on whether they form an Abrikosov vortex lattice. Although bulk lead (Pb) is classified as a prototypical type-I superconductor, we show that its two-band superconductivity allows for single-flux-quantum and multiple-flux-quanta vortices in the intermediate state at millikelvin temperature. Using scanning tunneling microscopy, the winding number of individual vortices is determined from the real space wave function of its Caroli–de Gennes–Matricon bound states. This generalizes the topological index theorem put forward by Volovik for isotropic electronic states to realistic electronic structures. In addition, the bound states due to the two superconducting bands of Pb can be separately detected and the two gaps close independently inside vortices. This yields strong evidence for a low interband coupling.

The Journal of Physical Chemistry C 123(31) 18939-18950 2019年7月 査読有り最終著者責任著者Crown-ether (CR) ring molecules are known as host molecules for capturing guest species inside the ring. So far CR molecular films have only been grown by drop-casting a CR solution on an inert substrate in air which offers little control over the molecular structure. Here we report the successful growth of a well-ordered CR molecular array on an atomically flat and clean noble metal Cu(111) substrate at 300 K in ultra-high vacuum (UHV), using 4,4′,5,5′-tetrabromodibenzo[18] crown-6 ether (Br-CR). The adsorption, self-assembly, and electronic structures of Br-CR were studied by means of UHV low-temperature scanning tunneling microscopy and spectroscopy, low electron energy diffraction, and angle-resolved ultraviolet photoemission spectroscopy. We found that (1) the Br-CR ring, which is bent both in the crystal and gas phase, flattens upon adsorption on Cu(111). Density functional theory reveals that the two benzene groups of the molecule lie flat on the surface such as to maximize the substrate-molecule interaction. (2) The moderate molecule–substrate interaction allows thermal diffusion of the Br-CR molecules, resulting in the formation of self-assembled monolayer islands with 7 × 4 superstructure. (3) While the deposition of 0.05 ML Br-CR forms multidomain islands with disordered defects, a drastic improvement occurred at 0.25 ML, where only atomically flat single-domain islands were grown. This Br-CR flat ring cavity array could become a template for designing novel two-dimensional arrays of desired guest atoms, ions, or functionalized molecules.

Review of Scientific Instruments 90 063701 2019年6月 査読有り最終著者責任著者A tungsten (W) tip has been used as a standard tip probe because of its robustness at the highest boiling temperature; the use cases include a field emission (FE) electron source for scanning electron microscopy (SEM) and a scanning probe microscopy tip. The W tip probe has generally been fabricated through a chemical etching process with aqueous solutions. In this study, we propose a new method—flame etching. Without using aqueous solutions, a W tip probe was successfully fabricated within 3 s in air, which is very fast and convenient, and beneficial for mass production (additionally, no expensive setup is necessary). A W tip probe was obtained simply by putting a W wire into an oxygen-liquefied petroleum (O2+LP) gas flame (giving the highest temperature of ∼2300 K) through a microtorch for a few seconds. The obtained W tip provided atomically resolved scanning tunneling microscopic images. Also, since FE electrons were detected by applying ∼106 V/m, the tip can be used as an FE-SEM source. Generation and vaporization of WO3 on the W surface are important processes to form a tip shape.

Journal of the Vacuum Society of Japan 60(5) 159-164 2017年 査読有り筆頭著者責任著者Spin-polarized STM (SP-STM) is a powerful tool to visualize sample spin-polarization vectors at an atomic scale. A dificulty of SP-STM measurement is how to fabricate a tip with a stable spin-polarization vector. In 1990's, first, many eforts were payed for a GaAs tip with optically pumping, but finally the GaAs tip did not detect sample spin polarization due to quenching of the spin-polarization at the GaAs tip apex. However, in 2000, a W tip coated by a magnetic thin film detected the spin-polarized tunneling current, and spin polarization images of magnetic atoms were successfully obtained. In 2016, more than 15 groups in the world can perform SP- STM measurements. History and issues for further development of SP-STM measurements are discussed.

表面科学 34(8) 443-448 2013年8月 査読有り招待有り筆頭著者最終著者責任著者Giant magnetoresistance (GMR) through a single phthalocyanine molecule (H2Pc) was studied by means of a spin-polarized scanning tunneling microscopy (STM) technique. Single molecular magnetic junction was fabricated by contacting a ferromagnetic STM tip to a single molecule on nano magnets. We obtained GMR of +60% and −50% through [Co/H2Pc/Co(111)] and [Fe/H2Pc/Mn(001)] junctions, respectively, in ultra-high vacuum at 4.6 K. Single organic molecules can be a new material for spintronics.

J. Magn. Soc. Jpn. 36(2) 100-103 2012年 査読有り招待有り筆頭著者責任著者Controlling metal magnet with electric field opens up a new pathway to fabricate metallic nonvolatile magnetic data-storage devices. Such magnetoelectric coupling has been studied mainly for insulators, e.g. complex multiferroic oxides. Although electric field applying to the bulk metals cannot go inside due to the screening by the conducting electrons, we found that magnetic phase of nano-scale iron metal magnets is able to be controlled by electric field pulses. All experiments were performed by scanning tunneling microscopy (STM) setup in ultra-high vacuum at 4K. Statistic switching of the magnetic phase between ferromagnetic bcc phase and layer-wise antiferromagnetic fcc phase as well as time response of the phase switching by a fast pulse were studied.

NATURE NANOTECHNOLOGY 6(3) 185-189 2011年3月 査読有りMagnetoresistance is a change in the resistance of a material system caused by an applied magnetic field. Giant magnetoresistance occurs in structures containing ferromagnetic contacts separated by a metallic non-magnetic spacer, and is now the basis of read heads for hard drives and for new forms of random access memory. Using an insulator (for example, a molecular thin film) rather than a metal as the spacer gives rise to tunnelling magnetoresistance, which typically produces a larger change in resistance for a given magnetic field strength, but also yields higher resistances, which are a disadvantage for real device operation. Here, we demonstrate giant magnetoresistance across a single, nonmagnetic hydrogen phthalocyanine molecule contacted by the ferromagnetic tip of a scanning tunnelling microscope. We measure the magnetoresistance to be 60% and the conductance to be 0.26G(o), where G(o) is the quantum of conductance. Theoretical analysis identifies spin-dependent hybridization of molecular and electrode orbitals as the cause of the large magnetoresistance.

Physical Review B 72(1) 2005年7月5日 査読有り筆頭著者In this work we explore by means of spin-polarized scanning tunneling microcopy/spectroscopy (SP-STM/STS) and ab initio calculations the magnetic and electronic properties of thin MnAu alloyed films. The MnAu films are produced by deposition of small amounts of Au at RT on a Mn(001) surface. On the scanning tunneling microscopy images the surface of the AuMn alloy presents a c(2×2) reconstruction. From the SP-STM/STS measurements we find out that the MnAu alloy layers are coupled antiferromagnetically with the layers above and below. Comparing the result from the ab initio calculations with the spin-polarized measurements we found that the origin of the magnetic contrast is due to a spin-polarized peak at 0.15eV above the Fermi level spatially placed on the Mn sites. In the calculations we also found that the magnetic moments of the Mn atoms are higher in the alloy layers than in the pure Mn films. © 2005 The American Physical Society.

ACTA PHYSICA POLONICA A 104(3-4) 231-243 2003年9月 査読有りThe surface states of 3d transition metals are studied by scanning tunneling microscopy and scanning tunneling spectroscopy. The results show that surface states can be used for chemical identification with high spatial resolution. The spin polarized nature of the surface states allows us to obtain magnetic contrast in scanning tunneling miroscopy imaging with near atomic resolution. For Cr(100) we found that the surface state close to the Fermi level can be explained by an orbital Kondo resonance surface state.

PHYSICAL REVIEW B 68(4) 045422 2003年7月 査読有りScanning tunneling spectroscopy is used to study the local electronic structure of Fe(001) whiskers. The influence of a voltage dependent background on the apparent peak energies in the dI/dV curves is discussed. A relation between this background and the apparent barrier height is established. The previously reported spin-polarized d(z)2-like surface state is shown to shift by an amount of 0.04 eV to higher energies at isolated oxygen impurities on the Fe(001) surface. The surface state disappears on both [100] and [110] directed steps. Finally, we investigated size effects by studying the behavior of the surface state on nanometer-sized Fe islands. Besides the surface-state quenching at the step edges, a peak shift to higher energies is observed for decreasing island sizes.

JAPANESE JOURNAL OF APPLIED PHYSICS PART 1-REGULAR PAPERS SHORT NOTES & REVIEW PAPERS 42(7B) 4688-4691 2003年7月 査読有りNormalized differential tunneling conductivities obtained with Fe-coated W tips show a spin-polarized peak around +0.8 V on ultrathin bet Mn films grown on Fe(001)-whiskers. This spin-polarized peak results in a clear magnetic contrast in spectroscopic images. Our normalization removes the influence of the tunneling probability and makes the spectroscopic curves most reliable for a derivation of the spin-resolved sample density of states (DOS) at positive voltages. From this analysis we conclude that the magnetic contrast in our spectroscopic maps is caused by a highly polarized DOS. Furthermore, a, tip polarization of about 15% is found.

PHYSICAL REVIEW B 67(16) 165403 2003年4月 査読有りScanning tunneling microscopy measurements show that the growth of about half a monolayer Au on Fe(001) at a temperature of 170 degreesC leads after a postanneal at 700 degreesC to an island free and homogeneously alloyed surface layer. The surface alloying is in contrast to the bulk where Au and Fe are immiscible. Strong chemical contrast in the images allows us to analyze the short-range order of this surface alloy. Two independent methods are considered: the first method extracts pair occupation probabilities directly from digitized images, the second method makes use of the autocorrelation of filtered images. Both methods lead to the same conclusion: only for the nearest-neighbor sites a strong preference for unlike species is found; for further sites the probabilities follow a random distribution. Scanning tunneling spectroscopy measurements on the alloyed AuFe surface are used to corroborate the interpretation of the chemical contrast. Furthermore, the spectroscopy results show that the Fe(001) surface state shifts to higher energies on areas where pure Fe patches are confined by Au atoms.

APPLIED PHYSICS LETTERS 82(9) 1437-1439 2003年3月 筆頭著者The present letter describes a method to make a spin-polarized scanning tunneling microscopy tip by applying voltage pulses between a W tip and a magnetic sample. This spin-polarized tip has the similar characteristics as an Fe-coated W tip, which was confirmed by observations of antiferromagnetically coupled ferromagnetic Mn(001) layers (>3 ML) grown on an Fe(001) whisker at 370 K. Furthermore, we demonstrate that these voltage pulses can vary the tip magnetization direction. (C) 2003 American Institute of Physics.

PHYSICAL REVIEW LETTERS 90(5) 056803 2003年2月 査読有り筆頭著者We report the observation of a magnetic contrast of up to 20% in the scanning tunneling spectroscopy dI/dV maps obtained with Fe-coated tips on Mn(001) layers grown on an Fe(001) whisker at 370 K. These nanometer resolution microscopy results show that the layers couple antiferromagnetically. By normalizing the dI/dV curves by tunneling probability functions, we found a spin-dependent peak on the body-centered-tetragonal (bct) Mn(001) surface at +0.8 V, whose high spin polarization gives rise to the dI/dV map contrast. Band structure calculations allow one to identify the +0.8 V peak as due to two spin-polarized d(z)(2) surface states.

SURFACE SCIENCE 501(1-2) 155-167 2002年3月 査読有りThe submonolayer growth of Mn on Fe(0 0 1) in the temperature range between 50 and 200 degreesC is studied by scanning tunneling microscopy and scanning tunneling spectroscopy. For growth temperatures above 100 degreesC, atomically resolved STM images with chemical contrast clearly reveal the incorporation of Mn atoms in the Fe(0 0 1) substrate. The fraction of place exchanged Mn atoms is observed to increase with growth temperature. Although on islands a c(2 x 2) structure forms locally which is attributed to an ordered MnFe surface alloy, long range order could not be obtained for the growth temperatures and coverages studied. Spectroscopy results are presented for clean Fe(0 0 1), pure Mn ad-islands, single incorporated Mn atoms and c(2 x 2)-ordered MnFe areas. In contrast to embedded Cr atoms in the Fe(0 0 1) surface [Phys. Rev. Lett. 76 (1996) 41751, isolated embedded Mn atoms do not lead to double peak structures in dI/dV curves. Nevertheless, on the ordered c(2 x 2) MnFe structure and the pure Mn monoatomic islands surface states are detected as peaks in the dI/dV and (dI/dV)/(I/V) curves. However, due to the strong influence of a tip-dependent background on these peaks. the corresponding surface state energies cannot be found directly from those curves. The real surface state energies were recovered by normalizing the measured dI/dV curves by fitted quadratic backgrounds. Thus, surface state energies of about +0.35 and +0.25 eV are estimated for pure Mn islands and alloyed MnFe areas, respectively. (C) 2002 Elsevier Science B.V. All rights reserved.

PHYSICAL REVIEW LETTERS 87(24) 246102-1 2001年12月 査読有りScanning tunneling microscopy studies on the growth of Au on Fe(001) are reported. A surface alloy is observed for submonolayer deposition (<0.5 monolayer) at temperatures higher than 370 K. This surface-confined alloy demixes when it is covered with Au and in combination with imperfect layer-by-layer growth a rough interface consisting of Au islands in and Fe islands on the original Fe(001) substrate is created. A real-space high resolution study of this buried interface is possible because of the large difference in interlayer spacing between bcc Fe(001) and fcc Au(001).

SURFACE SCIENCE 479(1-3) 33-42 2001年5月 査読有り筆頭著者Various surface configurations of Cs/p-GaAs(1 1 0) have been studied by scanning tunneling microscopy and scanning tunneling spectroscopy with an interest in relation to the photoelectron emission. The local work function is found to be 4.8, 3.3, and 3.3 eV from clean p-GaAs(1 1 0), Cs one-dimensional (1D) lines (Cs coverage of 0.23 ML), and partially-ordered Cs polygons (Cs coverage of 0.5 ML), respectively. It is understood that only a coherently c(4 x 4)-ordered Cs-polygon surface (Cs coverage of 0.6 and 0.7 ML) can emit photoelectrons due to a sufficient reduction of the local work function down to 1.3 eV to get the negative electron affinity state. The local work function image shows that the boundary of Cs atoms has a lower local work function than at the top of Cs atoms. (C) 2001 Elsevier Science B.V. All rights reserved.

Trans. Magn. Soc. Japan 1(1) 16-21 2001年 査読有りThe saturation spin polarization of secondary electrons from a clean Ni (110) surface was quantitatively measured at 0.094 after careful calibration of a compact Mott detector installed in an Auger electron analyzer for strict inspection of the cleanness of the surface. The spin-dependent mean absorption length of Ni (110) was deduced to be about four layers of Ni (110), that is, λ+= 1.016 nm and λ _= 0.972 nm for the majority spin and minority spin electrons, respectively, from the primary electron energy dependence of the yield and the asymmetry of secondary electrons. The saturation spin polarization was reduced to 0.060, that is, 64% of that for the clean Ni (110) surface, after only 1 hour in a UHV chamber (2×10-7Pa) following a cleaning procedure, for sub-mono-layer oxygen-chemisorbed Ni (110). A model of anti-ferromagnetic Ni spin moments resulting from 180-degree super-exchange through oxygen atoms in the first layer, based on reported STM observations of Ni-O atomic arrangement, is proposed for use in further investigations to explain this drastic reduction in the polarization, which must be very sensitive to the surface magnetic configuration.
