Pressure Study of BiS2-Based Superconductors Bi4O4S3 and La(O,F)BiS2
Hisashi Kotegawa, Yusuke Tomita, Hideki Tou +6
We report the electrical resistivity measurements under pressure for the recently discovered BiS2-based layered superconductors Bi4O4S3 and La(O,F)BiS2. In Bi4O4S3, the transition…
Anion height dependence of Tc for the Fe-based superconductor
Y. Mizuguhci, Y. Hara, K. Deguchi +6
We have established a plot of the anion height dependence of Tc for the typical Fe-based superconductors. The plot appeared a symmetric curve with a peak around 1.38 A. Both data a…
Contrasting Pressure Effects in Sr2VFeAsO3 and Sr2ScFePO3
H. Kotegawa, T. Kawazoe, H. Tou +4
We report the resistivity measurements under pressure of two Fe-based superconductors with a thick perovskite oxide layer, Sr2VFeAsO3 and Sr2ScFePO3. The superconducting transition…
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,…
Effect of Uniaxial Stress for Pressure-Induced Superconductor SrFe_2As_2
H. Kotegawa, T. Kawazoe, H. Sugawara +2
We report that the pressure-temperature phase diagram of single-crystalline SrFeAs is easily affected by the hydrostaticity of a pressure-transmitting medium. For all of th…
Abrupt Emergence of Pressure-Induced Superconductivity of 34 K in SrFe2As2: A Resistivity Study under Pressure
H. Kotegawa, H. Sugawara, H. Tou
We report resistivity measurement under pressure in single crystals of SrFe_2As_2, which is one of the parent materials of Fe-based superconductors. The structural and antiferromag…
