The kinetics of two-dimensional conduction electrons in quantizing magnetic and electric fields is studied with due account of spin–orbit interaction. Equations of energy balance for a spin subsystem and transverse spin components are derived and solved. Charge carriers spins are found to be polarized by an electric field in a quantizing magnetic field. General expressions for transverse relaxation time of conduction electrons spins in high magnetic fields are obtained. It is shown that the spin polarization oscillations in a quantizing magnetic field become anomalously large.
