Pressure-dependent magnetization and magnetoresistivity studies on the tetragonal FeS (mackinawite): revealing its intrinsic metallic character
S. J. Denholme, H. Okazaki, S. Demura +9
The transport and magnetic properties of the tetragonal FeS were investigated using magnetoresistivity and magnetization within 2300 K, 70 kOe and $P\le…
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,…
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.…
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…
