| Abstract: | We report some results of magnetoabsorption and magnetoreflectivity measurements performed on CdMnTe crystals in magnetic field up to 30 T. The exciton energy at low fields in materials containing magnetic ions is calculated on the basis of the Altarelli-Lipari model and compared with the experimental results. It is shown that spin mixing in degenerate bands strongly affects magnetoabsorption. |
