Evolution of superconductivity in isovalent Te-substituted KxFe2-ySe2 crystals
Toshinori Ozaki, Hiroyuki Takeya, Keita Deguchi +8
We report the evolution of superconductivity and the phase diagram of the KxFe2-ySe2-zTez (z=0-0.6) crystals grown by a simple one-step synthesis. No structural transition is obser…
BiS2 - based superconductivity in F-substituted NdOBiS2
Satoshi Demura, Yoshikazu Mizuguchi, Keita Deguchi +12
We have successfully synthesized a new BiS2-based superconductor NdOBiS2 with F-doping. This compound is composed of superconducting BiS2 layers and blocking NdO layers, which indi…
Electrodeposition as a new route to synthesize superconducting FeSe
Satoshi Demura, Hiroyuki Okazaki, Toshinori Ozaki +9
We have successfully synthesized FeSe films by the electrochemical deposition in the electrolyte containing FeCl_{2}\cdot4H_{2}O, SeO_{2} and Na_{2}SO_{4}. The composition ratio of…
Evidence of Inhomogeneous Superconductivity in FeTeSe Thin Film Using Scotch-Tape Method
H. Okazaki, T. Watanabe, T. Yamaguchi +8
We have fabricated thin films of FeTeSe using a scotch-tape method. The superconductivities of the thin films are different from each other although these films were fa…
Tartaric acid in red wine as one of the key factors to induce superconductivity in FeTe0.8S0.2
Keita Deguchi, Tohru Okuda, Yasuna Kawasaki +10
The red wine dependence of superconductivity in FeTe0.8S0.2 was investigated. Samples with a higher shielding volume fraction had a tendency to show a higher concentration of tarta…
One-step synthesis of KxFe2-ySe2 single crystals for high critical current density
Toshinori Ozaki, Hiroyuki Takeya, Hiroyuki Okazaki +7
We have established a simple process that allows for the one-step synthesis of KxFe2-ySe2 single crystals, which exhibit high critical current density Jc. The post annealing and qu…
