Abstracts

EN

A simple and convenient model is proposed to elucidate the optical characteristics of Cd_{1-x}Mn_xTe crystals using experimental data on light reflection in magnetic field. The model is based on the quasi-oscillator concept accounting both for the exciton and fundamental absorption edge contributions. The energy dependencies of refraction index and absorption coefficient are presented for Mn mole fraction x=20% at the magnetic field values up to 5 T.
