Intrinsic pinning property of FeSe0.5Te0.5
M. Migita, Y. Takikawa, M. Takeda +5
The intrinsic pinning properties of FeSe0.5Te0.5, which is the superconductor with Tc of about 14 K, were studied by the analysis of magnetization curves by the extended critical s…
A study of electronic structure of FeSeTe chalcogenides by Fe and Se K-edge x-ray absorption near edge structure measurements
B. Joseph, A. Iadecola, L. Simonelli +4
Fe K-edge and Se K-edge x-ray absorption near edge structure (XANES) measurements are used to study FeSeTe electronic structure of chalcogenides. An intense Fe K-edge…
Microstructure and transport properties of FeTe0.5Se0.5 superconducting wires fabricated by ex-situ Powder-in-tube process
T. Ozaki, K. Deguchi, Y. Mizuguchi +2
We fabricated FeTe0.5Se0.5 superconducting wires using ex-situ Powder-in-tube method with an Fe sheath. It was amazing that superconducting current was observed in the as-drawn wir…
Evidence of local structural inhomogeneity in FeSe(1-x)Te(x) from extended x-ray absorption fine structure
B. Joseph, A. Iadecola, A. Puri +4
Local structure of FeSe(1-x)Te(x) has been studied by extended x-ray absorption fine-structure (EXAFS) measurements as a function of temperature. Combination of Se and Fe K edge EX…
Weak superconducting fluctuations and small anisotropy of the upper critical fields in an Fe1.05Te0.85Se0.15 single crystal
T. Kida, M. Kotani, Y. Mizuguchi +2
We have investigated the temperature dependence of the resistive upper critical fields () for an FeTeSe single crystal, which exhibit…
