Moisture-induced superconductivity in FeTe0.8S0.2
Yoshikazu Mizuguchi, Keita Deguchi, Shunsuke Tsuda +2
Moisture-induced superconductivity was observed in FeTe0.8S0.2. With exposing the sample to the air, the zero resistivity temperature and the superconducting volume fraction were e…
Local density of states and superconducting gap in the iron chalcogenide superconductor FeSeTe observed by scanning tunneling spectroscopy
Takuya Kato, Yoshikazu Mizuguchi, Hiroshi Nakamura +3
We report on the first investigation of the quasiparticle local density of states and superconducting gap in the iron chalcogenide superconductor FeSeTe ($T_{…
Mossbauer studies on FeSe and FeTe
Yoshikazu Mizuguchi, Takao Furubayashi, Keita Deguchi +3
We carried out 57Fe Mossbauer measurements for FeSe and Fe1.08Te to investigate the magnetic properties. There was no sign of magnetic ordering above 4.2 K for superconducting FeSe…
Pressure effects on FeSe family superconductors
Yoshikazu Mizuguchi, Fumiaki Tomioka, Keita Deguchi +3
We investigated the pressure effects on the FeSe superconductor and the related compounds. Pressure dependence of superconducting transition temperature (Tc) for FeSe0.8S0.2 exhibi…
Fabrication of the iron-based superconducting wire using Fe(Se, Te)
Yoshikazu Mizuguchi, Keita Deguchi, Shunsuke Tsuda +4
We have fabricated the Fe(Se, Te) superconducting wire by a special process based on a powder-in-tube method. The pure Fe tube plays the role of not only the sheath but also the ra…
Upper critical fields of the 11-system iron-chalcogenide superconductor FeSeTe
Takanori Kida, Takahiro Matsunaga, Masayuki Hagiwara +3
We have performed electrical resistivity measurements of a polycrystalline sample of FeSeTe, which exhibits superconductivity at K, in magneti…
Precise Pressure Dependence of the Superconducting Transition Temperature of FeSe: Resistivity and ^77Se--NMR Study
S. Masaki, H. Kotegawa, Y. Hara +4
We report the precise pressure dependence of FeSe from a resistivity measurement up to 4.15 GPa. Superconducting transition temperature (T_c) increases sensitively under pressure,…
Successive phase transitions under high pressure in FeTe0.92
Hironari Okada, Hiroyuki Takahashi, Yoshikazu Mizuguchi +2
We performed magnetization and electrical resistivity measurements under high pressures of up to 19 GPa for FeTe0.92. The compound shows an anomaly in magnetization and resistivity…
Pressure evolution of low-temperature crystal structure and bonding of 37 K FeSe superconductor
S. Margadonna, Y. Takabayashi, Y. Ohishi +6
FeSe with the PbO structure is a key member of the family of new high- iron pnictide and chalcogenide superconductors, as while it possesses the basic layered structural motif…
