Abstract:Band parameters and the exchange integrals of Cd0.95Mn0.05Se are evaluated using magnetoabsorption measurement results. The anisotropy of the exchange interaction for valence band electrons and the magnetic field dependent wave function mixing coefficients are obtained. The use of a quasi-cubic model for describing a CdMnSe crystal in the presence of magnetic field is shown to be unjustified.
