Superconductivity in Fe1+dTe0.9Se0.1 induced by deintercalation of excess Fe using alcoholic beverage treatment
K. Deguchi, S. Demura, H. Hara +8
Superconductivity in polycrystalline Fe1+dTe0.9Se0.1 was enhanced by heating in alcoholic beverages. We found that part of the excess Fe was deintercalated from the interlayer site…
Evolution of superconductivity in LaO1-xFxBiS2 prepared by high pressure technique
K. Deguchi, Y. Mizuguchi, S. Demura +10
Novel BiS2-based superconductors LaO1-xFxBiS2 prepared by the high pressure synthesis technique were systematically studied. It was found that the high pressure annealing strongly…
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…
BiS2 - based superconductivity in F-substituted NdOBiS2
Satoshi Demura, Yoshikazu Mizuguchi, Keita Deguchi +12
We have successfully synthesized a new BiS2-based superconductor NdOBiS2 with F-doping. This compound is composed of superconducting BiS2 layers and blocking NdO layers, which indi…
