Violation of local reciprocity in charge-orbital interconversion
Hisanobu Kashiki, Hiroki Hayashi, Dongwook Go +2
We demonstrate a violation of local reciprocity in the interconversion between charge and orbital currents. By investigating orbital torque and orbital pumping in W/Ni bilayers, we…
Identification of orbital pumping from spin pumping and rectification effects
Nils Keller, Arnab Bose, Nozomi Soya +9
The recently predicted mechanism of orbital pumping enables the generation of pure orbital current from a precessing ferromagnet (FM) without the need for electrical current inject…
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…
Current-induced torque originating from orbital current
Yuya Tazaki, Yuito Kageyama, Hiroki Hayashi +4
The electrical manipulation of magnetization by current-induced spin torques has given access to realize a plethora of ultralow power and fast spintronic devices such as non-volati…
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…
