Axis thermal expansion switching in transition-metal zirconides TrZr2 by tuning the c/a ratio
Hiroto Arima, Md. Riad Kasem, Yoshikazu Mizuguchi
This study examines the temperature-dependent evolution of the lattice constants for various CuAl2-type compounds, including NiZr2, (Co,Rh,Ir)Zr2, (Fe,Co,Rh,Ir)Zr2, and (Co,Ni,Cu,R…
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…
Superconductivity of high-entropy-alloy-type transition-metal zirconide (Fe,Co,Ni,Cu,Ga)Zr2
Md. Riad Kasem, Hiroto Arima, Yoichi Ikeda +2
We synthesized a new high-entropy-alloy-type (HEA-type) superconductor (Fe,Co,Ni,Cu,Ga)Zr2 with a Tc of 2.9 K. The EDX analyses revealed that the actual composition of the transiti…
Anomalous thermal expansion in a CuAl2-type superconductor CoZr2
Yoshikazu Mizuguchi, Md. Riad Kasem, Yoichi Ikeda
In this work, we show that the CuAl2-type superconductor CoZr2 and alloyed systems exhibit anomalous thermal expansion in a wide temperature range. We performed neutron powder diff…
Tuning of Carrier Concentration and Superconductivity in High-Entropy-Alloy-Type Metal Telluride (AgSnPbBi)(1-x)/4InxTe
Md. Riad Kasem, Ryota Ishii, Takayoshi Katase +2
High-entropy-alloy-type (HEA-type) compound superconductors have been drawing much attention as a new class of exotic superconductors with local structural inhomogeneity. NaCl-type…
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…
