Absence of Tc-Pinning Phenomenon Under High Pressure in High-Entropy REO0.5F0.5BiS2 Layered Superconductor

Yoshikazu Mizuguchi, Kazuki Yamane, Ryo Matsumoto +7

Recently, robustness of superconductivity (transition temperature, Tc) under high pressures has been observed in high-entropy alloy (HEA), bcc-type Ti-Zr-Hf-Nb-Ta, and HEA-type com…

Glassy atomic vibrations and blurry electronic structures created by local structural disorders in high-entropy metal telluride superconductors

Yoshikazu Mizuguchi, Hidetomo Usui, Rei Kurita +10

The motivation of this work is our recent observation of the robustness of superconductivity in a High-entropy (HE) superconductor Ag0.2In0.2Sn0.2Pb0.2Bi0.2Te (CsCl-type) to extern…

Lattice Anharmonicity in BiS2-Based Layered Superconductor RE(O,F)BiS2 (RE = La, Ce, Pr, Nd)

Fysol Ibna Abbas, Kazuhisa Hoshi, Aichi Yamashita +9

We studied Grüneisen parameter (γG) to investigate lattice anharmonicity in a layered BiS2-based superconductor system REO1-xFxBiS2 (RE = La, Ce, Pr, Nd), where in-plane chemical p…

Improvement of upper critical field by the compositionally-complex-alloy concept in A15 superconductor V3X (X: Al, Si, Ga, Ge, Sn)

Yuki Nakahira, Ryosuke Kiyama, Aichi Yamashita +5

Compositionally complex alloys (CCAs) are a new category of high-entropy materials containing more than two high-entropy phases in an alloy sample. We applied the concept of CCA to…
