Dynamics of spin interactions in Mn2+ doped CdMnTe semiconductors studied with optically detected magnetic resonance

Analysis of photoluminescence changes observed at Mn2+ magnetic resonance is presented. CdMnTe samples of a different dimensionality are investigated. We discuss conditions of a strong magnetization quenching at the magnetic resonance and the role of Mn-free carriers spin interactions in spin relaxation processes. Concept of time-resolved experiment is introduced to determine times of spin relaxation.
