Spin Currents Induced by Nonuniform Rashba-Type Spin-Orbit Field
Kazuhiro Tsutsui, Akihito Takeuchi, Gen Tatara +1
We study the spin relaxation torque in nonmagnetic or ferromagnetic metals with nonuniform spin-orbit coupling within the Keldysh Green's function formalism. In non-magnet, the rel…
Topological charge pumping effect by the magnetization dynamics on the Surface of Three-Dimensional Topological Insulators
Hiroaki T. Ueda, Akihito Takeuchi, Gen Tatara +1
We discuss a current dynamics on the surface of a 3-dimensional topological insulator induced by magnetization precession of a ferromagnet attached. It is found that the magnetizat…
Spin Damping Monopole
Akihito Takeuchi, Gen Tatara
We present theoretical evidence that a magnetic monopole emerges in dynamic magnetic systems in the presence of the spin-orbit interaction. The monopole field is expressed in terms…
