"Current-Induced Spin Polarization of 2DEG in Perpendicular Magnetic Field"

Maxim Vavilov , Yale University
[Host: Jongsoo Yoon]
An electric field applied to a two-dimensional electron gas with spin-orbit coupling generates spin magnetization. Based on a quantum kinetic equation, we study the dependence of the magnitude and direction of the spin magnetization on the strength of a perpendicular magnetic field. We show that as magnetic field increases, the magnitude of the magnetization decreases. However, in sufficiently strong magnetic fields, the magnetization acquires a giant oscillating component; the amplitude of this component may exceed the magnetization at zero magnetic field. The large amplitude of magnetization oscillations is related to the enhanced electron-hole asymmetry in quantizing magnetic fields.
