Doping Dependence of Upper Critical Field of High-Tc Cuprate Bi2+xSr2-xCaCu2O8+d Estimated from Irreversibility Field at Zero Temperature
Junichiro Kato, Shigeyuki Ishida, Tatsunori Okada +12
We investigated the temperature (T) dependence of the irreversibility field Hirr(T) in high-critical-temperature cuprate Bi2+xSr2-xCa1-yYyCu2O8+d (Bi-2212) single crystals over a w…
Electronic States and Energy Dissipations of Vortex Core in Pure FeSe Single Crystals Investigated by Microwave Surface Impedance Measurements
Tatsunori Okada, Yoshinori Imai, Takahiro Urata +3
In order to clarify electronic states and energy dissipations due to a motion of a vortex core in pure FeSe, which is a candidate superconductor possessing a super-clean core, we m…
Competition of superconductivity with the structural transition in Mo3Sb7
G. Z. Ye, J. -G. Cheng, J. -Q. Yan +8
Prior to the superconducting transition at Tc = 2.3 K, Mo3Sb7 undergoes a symmetry-lowering, cubic-to-tetragonal structural transition at Ts = 53 K. We have monitored the pressure…
Investigation of the Superconducting Gap Structure in SrFe(AsP) by Magnetic Penetration Depth and Flux Flow Resistivity Analysis
Hideyuki Takahashi, Tatsunori Okada, Yoshinori Imai +4
We measured the microwave surface impedances and obtained the superfluid density and flux flow resistivity in single crystals of a phosphor-doped iron-based superconductor SrFe…
