Description:
Author(s): Tian-Yue Chen, Tsao-Chi Chuang, Ssu-Yen Huang, Hung-Wei Yen, and Chi-Feng Pai High-entropy alloys (HEAs) with three to five nearly equimolar components have garnered interest in the past few years, due to their great material strength and tremendously tunable composition. Most work so far has focused on mechanical and structural properties rather than electrical transport, but recent studies indicate that HEAs possess unexpected superconductivity and magnetism. The authors’ experiments demonstrate that amorphous Ta-Nb-Hf-Zr-Ti can provide a sizable spin Hall effect, and supports magnetization switching via the induced spin-orbit torque, making it an interesting candidate for spintronic memory devices.
