摘要：
Optical orientation of excitons in quantum wells CdTe/CdMnTe has been observed in a steady-state regime. The luminescence polarization arising due to optical orientation of exciton angular momenta under optical pumping has been studied as a function of excitation quantum energy and transverse magnetic field. The magnetic depolarization of exciton radiation has been qualitatively understood by separate decay of electron and hole angular momenta taking into account the magnetic field induced mixing of involved states. The observation of luminescence linear polarization confirms this interpretation.
