Surface Rashba-Edelstein Spin-Orbit Torque Revealed by Molecular Self-Assembly
Satoshi Haku, Atsushi Ishikawa, Akira Musha +3
We report the observation of a spin-orbit torque (SOT) originating from the surface Rashba-Edelstein effect. We found that the SOT in a prototypical spin-orbitronic system, a Pt/Co…
Spin-orbit torques originating from bulk and interface in Pt-based structures
Hiroki Hayashi, Akira Musha, Hiroto Sakimura +1
We investigated spin-orbit torques in prototypical Pt-based spintronic devices. We found that, in Pt/Ni and Pt/Fe bilayers, the damping-like torque efficiency depends on the thickn…
Extrinsic-Intrinsic Crossover of the Spin Hall Effect Induced by Alloying
Akira Musha, Yusuke Kanno, Kazuya Ando
We report the observation of the crossover between the extrinsic and intrinsic spin Hall effect induced by alloying. We found that the spin Hall angle, the ratio of the spin Hall c…
Spin absorption at ferromagnetic-metal/platinum-oxide interface
Akio Asami, Hongyu An, Akira Musha +2
We investigate the absorption of a spin current at a ferromagnetic-metal/Pt-oxide interface by measuring current-induced ferromagnetic resonance. The spin absorption was characteri…
Intrinsic spin-orbit torque arising from Berry curvature in metallic-magnet/Cu-oxide interface
Tenghua Gao, Alireza Qaiumzadeh, Hongyu An +4
We report the observation of the intrinsic damping-like spin-orbit torque (SOT) arising from the Berry curvature in metallic-magnet/CuO heterostructures. We show that a robust…
