Orbital Pumping by Magnetization Dynamics in Ferromagnets
Dongwook Go, Kazuya Ando, Armando Pezo +3
We show that dynamics of the magnetization in ferromagnets can pump the orbital angular momentum, which we denote by orbital pumping. This is the reciprocal phenomenon to the orbit…
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…
Orbital Rashba effect in surface oxidized Cu film
Dongwook Go, Daegeun Jo, Tenghua Gao +4
Recent experimental observation of unexpectedly large current-induced spin-orbit torque in surface oxidized Cu on top of a ferromagnet suggested a possible role of the orbital Rash…
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…
