Universal Phase Diagram and Reentrant Superconductivity of layer Hydrated NaCoOHO
Hiroto Ohta, Chishiro Michioka, Yutaka Itoh +1
We report duration dependence of superconductivity in a 43 \% humidity atmosphere and Co nuclear quadrupole resonance (NQR) of polycrystalline samples of layer hydrated…
Magnetic and Superconducting Properties of Single Crystals of FeTeSe System
Jinhu Yang, Mami Matsui, Masatomo Kawa +7
The spin-fluctuation effect in the Se-substituted system FeTeSe ( = 0, 0.05, 0.12, 0.20, 0.28, 0.33, 0.45, 0.48 and 1.00; ) has been studied by th…
Unconventional Superconductivity in the Novel Layered Superconductor Fe(Te-Se) Investigated by Te NMR on the Single Crystal
Chishiro Michioka, Hiroto Ohta, Mami Matsui +3
We have performed Te NMR on a single crystal of the novel layered superconductor FeTeSe for the first time. The spin parts of the Knight shifts f…
Novel phase diagram of superconductor NaxCoO2-yH2O in a 75 % relative humidity
Hiroto Ohta, Chishiro Michioka, Yutaka Itoh +1
We succeeded in synthesizing the powder samples of bilayer-hydrate sodium cobalt oxide superconductors NaxCoO2-yH2O with Tc = 0 ~ 4.6 K by systematically changing the keeping durat…
