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…
Time-domain observation of ballistic orbital-angular-momentum currents with giant relaxation length in tungsten
Tom S. Seifert, Dongwook Go, Hiroki Hayashi +5
The emerging field of orbitronics exploits the electron orbital momentum . Compared to spin-polarized electrons, may allow magnetic-information transfera w…
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…
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…
