Anomalous sign inversion of spin-orbit torque in ferromagnetic/nonmagnetic bilayer systems due to self-induced spin-orbit torque
Motomi Aoki, Ei Shigematsu, Ryo Ohshima +3
Self-induced spin-orbit torques (SI-SOTs) in ferromagnetic (FM) layers have been overlooked when estimating the spin Hall angle (SHA) of adjacent nonmagnetic (NM) layers. In this w…
All-electric spin device operation using the Weyl semimetal, WTe, at room temperature
Kosuke Ohnishi, Motomi Aoki, Ryo Ohshima +4
Topological quantum materials (TQMs) possess abundant and attractive spin physics, and a Weyl semimetal is the representative material because of the generation of spin polarizatio…
Observation of gigantic spin conversion anisotropy in bismuth
Naoki Fukumoto, Ryo Ohshima, Motomi Aoki +9
Whilst the g-factor can be anisotropic due to the spin-orbit interaction (SOI), its existence in solids cannot be simply asserted from a band structure, which hinders progress on s…
