Profile Summary 【 Display / hide

  • Our primary purpose is discovery of new superconductors (e. g. MgB2, iron-based oxypnictide, cuparate). An approach to the purpose is improvements of sample synthesis procedures using solid state reaction & characterization of inorganic materials. We focus on a relation between crystallographic “local” structures (a factor of hyperfine structures) and electronic and/or magnetic structures of homogeneous crystals. This approach is the most reliable way to demonstrate new electronic materials.

    鉄系高温超伝導体の転移温度(Tc)は55 Kに上る。この値は液体窒素の沸点よりは低いが液体水素の沸点20.28 Kの2倍以上の値である。現在、Nb-TiやNb3Snなどの合金や金属間化合物を利用した超伝導線材が普及しているが、既存の超伝導材料は安定動作に高価な液体ヘリウムを冷媒として必要とする。しかし, 鉄系高温超伝導体はヘリウムを使用せずに安定動作する超伝導線材候補として有望である。

     View Summary

    Semiconducting mixed anion layered compounds (MALC) LaCu1-delta S0.5Se0.5O are synthesized via solid state reaction. We synthesized several nominal LaCu1-deltaS0.5Se0.5O (delta = 0, delta~ 0.01, and delta~ 0.02). A degenerated semiconducting bulk LaCu1-deltaS0.5Se0.5O appears at delta~ 0.01. p-type carriers are doped due to Cu deficient Cu1-deltaS0.5Se0.5 layers in LaCu1-deltaS0.5Se0.5O. In-gap states, which dominate electrical conduction, are observed at energy ~0.5 eV higher than that of the valence band in an energy band diagram for delta~ 0.01.

    The thermoelectric transport properties of the van der Waals-type layered rhombohedral SnAs-based compound, EuSn2As2, have been investigated. A densified polycrystalline sample of EuSn2As2 with porosity (phgr) of 2.4(9) vol.% exhibited
    a weak orientation to the c-axis for hexagonal coordination system; the weak orientation is parallel (P∥) to the pressing direction of hot pressing. Measurements of electrical resistivity (ρ), Seebeck coefficient (S),
    and thermal conductivity (κ) were conducted perpendicular (P⊥) to the pressing direction. The experimental values of ρ and S exhibit metallic temperature dependence and p-type carrier polarity. The power factor (P) was 0.51(8) mW m−1 K−2 at 673(4) K. Using the Wiedemann–Franz–Lorenz law, the phonon thermal conductivity (κph) was estimated to be 0.4(6) W m−1 K−1 at 673(6) K. The dimensionless figure of merit, ZT, was 0.092(17) at 673(3) K.

  • Investigations of arsenic substitution on the physical, electrical and magnetic properties of Bi-2212 superconductors

    Joint Work, Accepted,  ISSN  01411594

     View Summary

    The effect of Arsenic substitution on the properties of Bi-2212 superconductors was studied. Solid-state reaction technique was used for the synthesis of Bi2−xAsxSr2Ca1.1Cu2.1O8 samples, x = 0, 0.1, 0.2 and
    0.4. The X-ray diffraction confirmed the formation of the tetragonal phase of Bi-2212 superconductors. The decrement in the c parameter confirmed that As insertions were introduced into the Bi sites of the
    system. The grain morphology of the surface was analysed by scanning electron microscopy, where the amount of arsenic increases with As substitution. The superconducting transition temperature (Tc) was
    determined from the DC-electrical resistivity by the standard four-probe technique. Tc was enhanced up to x = 0.1 above which it was suppressed. For magnetism, half magnetic-hysteresis loops were obtained by SQUID magnetometer at different temperatures (5 and 30 K). The hysteresis loops sizes increased with increasing Asconcentrations. The critical current density (Jc) and the flux pinning mechanisms were investigated via different models.

  • Computational chemical analysis on element-specific magnetic phases in a mixed anion layered compound superconductor, Sr2VFeAsO3-delta: II. the most stable site positions for oxygen and electronic density of states (in Japanese)

    Materials Science and Technology of Japan (Materials Science Society of Japan)  56 ( 6 ) 231 - 235 2019.12

    Research paper (scientific journal), Accepted,  ISSN  13474774

     View Summary

    Sr2VFeAsO3−δ(21113V) is a mixed anion layered compound containing a perovskite-related vanadium (V) oxide blocking layer in a unit cell. In the previous study, the magnetic stability of V and Fe in 21113V (delta = 0, 0.25, 0.50) was theoretically verified on the density functional theory (DFT). In this study, we demonstrated the most stable site positions in the crystal structure including deficient oxygen. In delta = 0.25, 0.50, the z position of oxygen is reproduced reported results, preciously. It is indicated that oxygen deficiency is inevitable in the reported 21113V with nominally delta = 0 samples. The oxygen deficiency of the apical sites for the perovskite-related structure expands the lattice constant c. We also demonstrated the density of states (DOS) of 21113V. Fe in 21113V contributes to electrical conduction and V does not contribute to electrical conduction. Except for delta = 0, V in 21113V exhibits the ferrimagnetic phase (Ferri.) with spontaneous magnetic polarization.

     View Summary

    In a history of superconductors 1911-2017, Fe-based superconductor ReFePnO1-xFx (Re: rare earth, Pn: Pnictogen) exhibits relative high superconducting transition temperatures (Tc)  58 K under ambient pressure. Electron doping by substitution of O2- with F- was required for appearance of a superconducting phase with high Tc. The Tc and upper critical field of ReFePnO1-xFx are very attractive for applications as superconducting wires and tapes under high magnetic fields, although demonstration of practical superconducting wires is a tough challenge due to the difficulty in controlling the F contents during a processing for ex-situ powder in tube method. In 2017, Zhang et al reported that iron-based superconducting tapes with Cu sheath showed superconducting electrical current (Jc) ~ 18 kAcm2. It is noteworthy that the tapes are sintered at 300 deg. C.

  • A private story, discovery of iron-based high Tc superconductors II

    J. Cryo. Super. Soc. Jpn. 52 ( 6 ) 383 - 388 2017.11

    Introduction and explanation (scientific journal)

     View Summary

    After obtaining my doctorate in engineering from Keio University, I spent five years as a researcher at the Tokyo Institute of Technology, Suzukakedai Campus in Yokohama. During that time, I made the first report on a material system called iron-based high-temperature superconductors (Fe-SCs). Research on Fe-SCs is still hot topic in condensed matter physics. Now, I am continuing my research mainly on the fabrication of superconducting wire using Fe-SCs, while being distracted by some traditional affairs as a member of the faculty. Research on Fe-SCs has encouraged young researchers towards the further discovery of novel layered superconductors. This article was prepared by updating the content of “A Private Story, Discovery of Iron-based High Tc Superconductors” previously published in the membership journal of the Physical Society of Japan.

  • Temperature dependence of specific heat of EuSn2As2, a 2D antiferromagnetic compound

    W. Lee, R. Sakagami, K. Hirata, M. Matoba, Y. Kamihara

    The 45th annual conference on magnetics in Japan, 2021.09, Oral Presentation(general)

     View Summary

    After the discovery of graphene in 2004, 2D magnetic materials have earned a great interest among condensed matter physicists and material engineers due to their fascinating magnetic properties. The 2D magnetic materials have proven that they are worth of investigating as they gave birth to van der Waals materials or topological insulators. They are the
    type of materials that will introduce the new era for information and semiconductor technology.
    The previous paper by R. Sakagami et el1,2 demonstrated that EuSn2As2 samples were prepared from Eu ingots and
    Sn-As pallets through a liquid phase reaction in carbon crucibles within vacuum silica tubes.1) The resulting crystal structure of EuSn2As2 has a sandwich shape where top and bottom layers are Eu, and SnAs bilayer is positioned in between Eu layers.
    After successful synthesis, heat capacity measurement was performed through physical property measurement system (PPMS) from Quantum Design Inc. As shown in Figure 1, we observed that there was a sudden increase of heat capacity around 24 K which implies that antiferromagnetic transition occurred. It is noted that the heat capacity of EuSn2As2 tends to follow Dulong-Petit limit at high temperature which means ultimately it would reach C = 3nR where n is the number of atoms per formula and R is the molar-gas constant. Nevertheless, at sufficiently low temperature,
    Dulong-Petit law does not hold anymore. It is necessary to take account for lattice vibration which is involving Debye model into our formula to obtain a value of electronic heat capacity4), Sommerfeld constant. In the conference, we will demonstrate a Sommerfeld constant for polycrystalline EuSn2As2.
