Spin relaxation in a Rashba semiconductor in an electric field
Abstract
The impact of an external electric field on the spin relaxation in a disordered, two-dimensional electron system is studied within the framework of a field-theoretical formulation. Generalized Bloch equations for the diffusion and the decay of an initial magnetization are obtained. The equations are applied to the investigation of spin relaxation processes in an electric field.
