Abstract

A microscopic model calculation of the electric-field-induced nonequilibrium spin accumulation due to kinetic magnetoelectric effect in two-dimensional electron gases with both Rashba and Dresselhaus spin-orbit couplings is presented. The results show that by modulating the relative strength of the two different spin-orbit couplings, both the magnitude and the polarization direction of the nonequilibrium spin accumulation can be effectively controlled.
