High-Entropy Alloy Superconductors: Exotic Properties, Applications and Materials Design

Jiro Kitagawa received his B.S. degree in physics from Kyoto University, Japan, in 1993, and his M.S. and Ph.D. degrees in physics from the University of Tokyo, Japan, in 1995 and 1998, respectively. At the University of Tokyo, he carried out materials research on rare-earth intermetallic compounds showing quadrupolar orderings. After 2002 he was a research associate at Hiroshima University, Japan, and was then engaged in the study of material properties using the terahertz (THz) time-domain spectroscopic method and the development of THz devices. He was an associate professor at the Fukuoka Institute of Technology, Japan, from 2012 to 2014, and has been a professor there since 2015. His research interests include materials research on magnetic and superconducting materials. Currently, his work focuses on magnetism and superconductivity in high-entropy alloys and chemical control of the magnetic state in a compound with a complex crystal structure.

Yoshikazu Mizuguchi received his B.S. and M.S. degrees in physics in 2006 and 2008, respectively, and his Ph.D. degree in engineering from the University of Tsukuba, Japan, in 2010. At the University of Tsukuba, he carried out materials research on Fe-based superconductors and strongly correlated vanadium oxides. He joined Tokyo Metropolitan University, Japan, as an assistant professor in 2011, and is now an associate professor there. His research interests include materials research on superconducting and thermoelectric materials including high-entropy-alloy-type compounds.

Jiro Kitagawa於1993年獲得日本京都大學的物理學學士學位，並於1995年和1998年分別獲得日本東京大學的物理學碩士和博士學位。在東京大學，他進行了有關顯示四極序的稀土金屬間化合物的材料研究。2002年後，他成為日本廣島大學的研究助理，並從事使用太赫茲（THz）時域光譜法研究材料特性及THz設備的開發。他於2012年至2014年擔任日本福岡科技大學的副教授，自2015年起成為該校教授。他的研究興趣包括磁性和超導材料的材料研究。目前，他的工作重點是高熵合金中的磁性和超導性，以及在具有複雜晶體結構的化合物中對磁態的化學控制。

Yoshikazu Mizuguchi於2006年和2008年分別獲得物理學學士和碩士學位，並於2010年獲得日本筑波大學的工程學博士學位。在筑波大學，他進行了有關鐵基超導體和強關聯鉻氧化物的材料研究。他於2011年加入日本東京 metropolitan 大學擔任助理教授，現在是該校的副教授。他的研究興趣包括超導和熱電材料的材料研究，包括高熵合金型化合物。
