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…
Pseudo-hydrodynamic flow of quasiparticles in semimetal WTe2 at room temperature
Young-Gwan Choi, Manh-Ha Doan, Gyung-Min Choi +1
Recently, much interest has emerged in fluid-like electric charge transport in various solid-state systems. The hydrodynamic behavior of the electronic fluid reveals itself as a de…
Observation of the orbital Hall effect in a light metal Ti
Young-Gwan Choi, Daegeun Jo, Kyung-Hun Ko +7
The orbital angular momentum is a core ingredient of orbital magnetism, spin Hall effect, giant Rashba spin splitting, orbital Edelstein effect, and spin-orbit torque. However, its…
Nonlinear optical Hall effect in Weyl semimetal WTe2
Young-Gwan Choi, Manh-Ha Doan, Youngkuk Kim +1
The ordinary Hall effect refers to generation of a transverse voltage upon exertion of an electric field in the presence of an out-of-plane magnetic field. While a linear Hall effe…
Picosecond spin Seebeck effect
Johannes Kimling, Gyung-Min Choi, Jack T. Brangham +5
We report time-resolved magneto-optic Kerr effect measurements of the longitudinal spin Seebeck effect driven by an interfacial temperature difference between itinerant electrons a…
