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…
Clarification as to why alcoholic beverages have the ability to induce superconductivity in Fe_{1+d}Te_{1-x}S_x
K. Deguchi, D. Sato, M. Sugimoto +12
To elucidate the mechanism as to why alcoholic beverages can induce superconductivity in Fe_{1+d}Te_{1-x}S_x samples, we performed component analysis and found that weak acid such…
