Spin Relaxation in a Two-Dimensional Electron Gas in a Perpendicular Magnetic Field

Abstract

We consider the problem of spin relaxation in a two-dimensional electron gas (2DEG) in a perpendicular magnetic field. We assume that the spin relaxation is induced by the Rashba spin-orbit (SO) interaction, which appears due to the inversion asymmetry of the confining potential. Our solution is based on a microscopic evaluation of the spin density response function of the 2DEG with impurities and SO interaction. We derive explicit expressions for the transverse and longitudinal spin relaxation rates. Our analysis shows, in particular, that the spin relaxation rates exhibit {\it magnetoquantum oscillations}, which are analogous to the Shubnikov-de Haas oscillations of the electrical resistivity. These oscillations can be observed, for example, in time-resolved optical experiments.
