High entropy effect on thermoelectric properties of nonequilibrium cubic phase of AgBiSe2-2xSxTex with x = 0-0.6
Asato Seshita, Aichi Yamashita, Takayoshi Katase +1
Silver bismuth diselenide (AgBiSe2) has much attention as an efficient thermoelectric material due to its low thermal conductivity. However, AgBiSe2 exhibits multiple crystal struc…
Vortex formation and exotic superconducting states in field-cooled Sn-Pb solders
Takumi Murakami, Md. Riad Kasem, Hiroto Arima +3
Formation of vortices is a typical phenomenon of type-II superconductors under magnetic fields (H). In contrast, type-I superconductors do not host vortices because of their Meissn…
Weak antilocalization induced by Se substitution in layered BiCh-based (Ch = S, Se) superconductors LaOFBiSSe
Kazuhisa Hoshi, Hiroto Arima, Noriyuki Kataoka +6
We report transport properties for layered BiCh2-based (Ch = S, Se) superconductors LaO1-xFxBiS2-ySey (x = 0.2, 0.5, y = 0-1.05) and the observation of weak antilocalization (WAL).…
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…
Estimation of Grüneisen parameter of high-entropy-alloy-type functional materials
F. I. Abbas, Y. Nakahira, A. Yamashita +9
In functional materials like thermoelectric materials and superconductors, the interplay between functionality, electronic structure, and phonon characteristics is one of the key f…
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…
