The Influence of Electric Field οn the Optical Spin Polarization of Electrons in a Diluted Magnetic Semiconductor

In this paper we present the results of theoretical calculations for spin polarization η of band electrons in diluted magnetic semiconductor subjected to a polarized light wave and a carrier-warming electric field E. It was shown that the maximum value of $η_{max}$ can be reached at a certain $E_{max}$ corresponding to the peak of the carrier drift velocity v(E). For the higher doping impurity concentration, the values of $η_{max}$ become lower due to the equivalent decrease of electron temperature.
