Increase in Tc and change of crystal structure by high-pressure annealing in BiS2-based superconductor CeO0.3F0.7BiS2
Joe Kajitani, Takafumi Hiroi, Atsushi Omachi +2
Recently, several types of BiS2-based superconductor such as Bi4O4S3, REO1-xFxBiS2 (RE: rare earth) and Sr1-xLaxFBiS2 have been discovered. In this study, we have investigated the…
Element Substitution Effect on Superconductivity in BiS2-Based NdO_{1-x}F_xBiS_2
Takafumi Hiroi, Joe Kajitani, Atsushi Omachi +2
Recently, new layered superconductors having a BiS2-type conduction layer have been discovered. NdO1-xFxBiS2 is a typical BiS2-based superconductor with a maximum Tc of 5.4 K. In t…
Stabilization of high-Tc phase of BiS2-based superconductor LaO0.5F0.5BiS2 using high-pressure synthesis
Yoshikazu Mizuguchi, Takafumi Hiroi, Joe Kajitani +3
High-quality polycrystalline samples of LaO0.5F0.5BiS2 were obtained using high-pressure synthesis technique. The LaO0.5F0.5BiS2 sample prepared by heating at 700 C under 2 GPa sho…
