Spin current driven by ultrafast magnetization of FeRh
Kyuhwe Kang, Hiroki Omura, Oukjae Lee +4
Laser-induced ultrafast demagnetization is an important phenomenon that probes arguably ultimate limits of the angular momentum dynamics in solid. Unfortunately, many aspects of th…
The domain-wall motion driven by a rotating field in a ferrimagnet
Munsu Jin, Ik-Sun Hong, Duck-Ho Kim +2
We theoretically study a ferrimagnetic domain-wall motion driven by a rotating magnetic field. We find that, depending on the magnitude and the frequency of the rotating field, the…
Identifying intrinsic and extrinsic mechanisms of anisotropic magnetoresistance with terahertz probes
Ji-Ho Park, Hye-Won Ko, Jeong-Mok Kim +7
Identifying the intrinsic and extrinsic origins of magneto-transport in spin-orbit coupled systems has long been a central theme in condensed matter physics. However, it has been e…
Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching
Soogil Lee, Min-Gu Kang, Dongwook Go +9
Spin Hall effect, an electric generation of spin current, allows for efficient control of magnetization. Recent theory revealed that orbital Hall effect creates orbital current, wh…
Theory of Current-Induced Angular Momentum Transfer Dynamics in Spin-Orbit Coupled Systems
Dongwook Go, Frank Freimuth, Jan-Philipp Hanke +7
Motivated by the importance of understanding competing mechanisms to current-induced spin-orbit torque in complex magnets, we develop a unified theory of current-induced spin-orbit…
Role of orbital hybridization in anisotropic magnetoresistance
Hye-Won Ko, Hyeon-Jong Park, Gyungchoon Go +3
We theoretically and numerically show that longitudinal orbital currents in ferromagnets depend on the magnetization direction, which contribute to the anisotropic magnetoresistanc…
