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,…
Observation of isosceles triangular electronic structure around excess iron atoms in FeTe
T. Machida, K. Kogure, T. Kato +8
We present scanning tunneling microscopy and spectroscopy studies around an individual excess Fe atom, working as a local perturbation, in the parent material of the iron-chalcogen…
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…
