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…
Analysis of interdiffusion between SmFeAsO0.92F0.08 and metals for ex situ fabrication of superconducting wire
Masaya Fujioka, Masanori Matoba, Toshinori Ozaki +3
We demonstrate the fabrication of superconducting SmFeAsO1-xFx (Sm-1111) wires by using the ex-situ powder-in-tube technique. Sm-1111 powder and a binder composed of SmF3, samarium…
Transport properties of iron-based FeTe0.5Se0.5 superconducting wire
T. Ozaki, K. Deguchi, Y. Mizuguchi +2
FeTe0.5Se0.5 superconducting wires have been fabricated using ex-situ PIT method with an Fe sheath. Among the other FeAs-based superconductor, FeTe0.5Se0.5 has great advantage for…
