Observation of orbital pumping
Hiroki Hayashi, Dongwook Go, Yuriy Mokrousov +1
Harnessing spin and orbital angular momentum is a fundamental concept in condensed matter physics, materials science, and quantum-device applications. In particular, the search for…
Observation of long-range orbital transport and giant orbital torque
Hiroki Hayashi, Daegeun Jo, Dongwook Go +5
Modern spintronics relies on the generation of spin currents through spin-orbit coupling. The spin-current generation has been believed to be triggered by current-induced orbital d…
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…
Role of interfacial oxidation in generation of spin-orbit torques
Satoshi Haku, Musha Akira, Tenghua Gao +1
We report that current-induced spin-orbit torques (SOTs) in heavy-metal/ferromagnetic-metal bilayers are strongly altered by the oxidation of the ferromagnetic layer near the inter…
Impact of inherent energy barrier on spin-orbit torques in magnetic-metal/semimetal heterojunctions
Tenghua Gao, Alireza Qaiumzadeh, Roberto E. Troncoso +9
Spintronic devices are based on heterojunctions of two materials with different magnetic and electronic properties. Although an energy barrier is naturally formed even at the inter…
Rashba-Edelstein Magnetoresistance in Metallic Heterostructure
Hiroyasu Nakayama, Yusuke Kanno, Hongyu An +4
We report the observation of magnetoresistance originating from Rashba spin-orbit coupling (SOC) in a metallic heterostructure: the Rashba-Edelstein (RE) magnetoresistance. We show…
Asymmetric Pt/Co/Pt structure as a platform for extracting pure spin Hall torque
Hongyu An, Hiroyasu Nakayama, Yusuke Kanno +3
We have quantitatively studied the spin-orbit torque purely generated by the spin Hall effect in a wide range of temperatures by intensionally eliminating the Rashba spin-orbit tor…
