Coexistence of bulk superconductivity and ferromagnetism in CeO1-xFxBiS2
Satoshi Demura, Keita Deguchi, Yoshikazu Mizuguchi +14
We show the observation of the coexistence of bulk superconductivity and ferromagnetism in CeO1-xFxBiS2(x = 0 - 1.0) prepared by annealing under high-pressure. In CeO1-xFxBiS2 syst…
Sulfur annealing effect for superconductivity in iron chalcogenide compounds
K. Deguchi, A. Yamashita, T. Yamaki +8
We discovered a novel annealing method for Fe-chalcogenide superconductors. It was found that sulfur annealing deintercalated excess Fe via formation of FeS2. Due to its specifics,…
Phase diagram and superconductivity at 58.1 K in α-FeAs free SmFeAsO1-xFx
Masaya Fujioka, Saleem James Denholme, Toshinori Ozaki +9
The Phase diagram of SmFeAsO1-xFx in terms of x is exhibited in this study. SmFeAsO1-xFx from x = 0 to x = 0.3 were prepared by low temperature sintering with slow cooling. The low…
α-FeAs-free SmFeAsO1-xFx by low temperature sintering with slow cooling
Masaya Fujioka, Saleem James Denholme, Toshinori Ozaki +9
We obtained amorphous-FeAs-free SmFeAsO1-xFx using a low temperature sintering with slow cooling. SmFeAsO1-xFx is sintered at 980 °C for 40 hours and cooled slowly down to 600 °C.…
