Abstract
The approach based on kinetic equations is used to describe spin polarization of conductionelectrons in a semiconductor doped with d or f atoms and subject to circularly polarized radiation.In the stationary state we find analytical expressions for the spin polarization of band electrons,ρe, and spin polarization of electrons in the impurity levels,ρi. It is shown that the degree of spin polarization of the band electrons is mainly determinedby the polarization type of the light. On the basis of numerical results we conclude thatρe and ρi are practically independent of the long-term relaxation processes in the subsystem ofmagnetic impurities.
