Charge current driven by spin dynamics in disordered Rashba spin-orbit system
Jun-ichiro Ohe, Akihito Takeuchi, Gen Tatara
Pumping of charge current by spin dynamics in the presence of the Rashba spin-orbit interaction is theoretically studied. Considering disordered electron, the exchange coupling and…
Mesoscopic Hall effect driven by chiral spin order
Jun-ichiro Ohe, Tomi Ohtsuki, Bernhard Kramer
A Hall effect due to spin chirality in mesoscopic systems is predicted. We consider a 4-terminal Hall system including local spins with geometry of a vortex domain wall, where stro…
Dynamics of a domain wall and spin-wave excitations driven by a mesoscopic current
Jun-ichiro Ohe, Bernhard Kramer
The dynamics of a domain wall driven by a spin-polarized current in a mesoscopic system is studied numerically. Spin-mixing in the states of the conduction electrons is fully taken…
Mesoscopic Stern-Gerlach spin filter by nonuniform spin-orbit interaction
Jun-ichiro Ohe, Masayuki Yamamoto, Tomi Ohtsuki +1
A novel spin filtering in two-dimensional electron system with nonuniform spin-orbit interactions (SOI) is theoretically studied. The strength of SOI is modulated perpendicular to…
Conductance fluctuations in the presence of spin scattering
J. Ohe, M. Yamamoto, T. Ohtsuki
Electron transport through disordered systems that include spin scatterers is studied numerically. We consider three kinds of magnetic impurities: the Ising, the XY and the Heisenb…
