Crystal Structure, Lattice Vibrations, and Superconductivity of LaOFBiS
J. Lee, M. B. Stone, A. Huq +8
Neutron scattering measurements have been performed on polycrystalline samples of the newly discovered layered superconductor LaOFBiS, and its nonsuperconduct…
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…
Effect of the indium addition on the superconducting property and the impurity phase in polycrystalline SmFeAsO1-xFx
Masaya Fujioka, Toshinori Ozaki, Hiroyuki Takeya +9
We report enhancement in the magnetic critical current density of indium added polycrystalline SmFeAsO1-xFx. The value of magnetic Jc is around 25 kA/cm2 at 4.2 K under self-magnet…
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…
Evolution of superconductivity in isovalent Te-substituted KxFe2-ySe2 crystals
Toshinori Ozaki, Hiroyuki Takeya, Keita Deguchi +8
We report the evolution of superconductivity and the phase diagram of the KxFe2-ySe2-zTez (z=0-0.6) crystals grown by a simple one-step synthesis. No structural transition is obser…
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…
