Robustness of superconductivity to external pressure in high-entropy-alloy-type metal telluride AgInSnPbBiTe5
Md. Riad Kasem, Yuki Nakahira, Hitoshi Yamaoka +7
High-entropy-alloy (HEA) superconductors are a new class of disordered superconductors. In this study, we investigate the robustness of superconducting states in HEA-type metal tel…
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…
Superconductivity in In-doped AgSnBiTe3 with possible band inversion
Tsubasa Mitobe, Kazuhisa Hoshi, Md. Riad Kasem +9
We investigated the chemical pressure effects on structural and electronic properties of SnTe-based material using partial substitution of Sn by Ag0.5Bi0.5, which results in lattic…
Improvement of local critical current density of REBa2Cu3O7-d by the increase in configurational entropy of mixing at the RE site
Aichi Yamashita, Yuta Shukunami, Yoshikazu Mizuguchi
REBa2Cu3O7-d (RE123, RE: rare earth) is one of the high-temperature superconductors with a transition temperature (Tc) exceeding 90 K. Because of its high Tc and large critical cur…
Anomalous broadening of specific heat jump at Tc in high-entropy-alloy-type superconductor TrZr2
Md. Riad Kasem, Aichi Yamashita, Taishi Hatano +3
A high-entropy-alloy-type (HEA-type) superconductor is new category of highly disordered superconductors. Therefore, finding brand-new superconducting characteristics in the HEA-ty…
Synthesis of new high-entropy alloy-type Nb3 (Al, Sn, Ge, Ga, Si) superconductors
Aichi Yamashita, Tatsuma D. Matsuda, Yoshikazu Mizuguchi
Studies on high-entropy alloy (HEA) superconductors have recently been increasing, particularly in the fields of materials science and condensed matter physics. To contribute to re…
Superconductivity in HEA-type compounds
Y. Mizuguchi, A. Yamashita
Since the discovery of superconductivity in a high-entropy alloy (HEA) Ti-Zr-Nb-Hf-Ta in 2014, the community of superconductor science has explored new HEA superconductors to find…
