Abstract
A theory of bound magnetic polarons (BMPs) in dilute magnetic semiconductors is formulated by applying the functional integral method (FIM). The effects of the antiferromagnetic Mn-Mn interaction on BMPs in dilute systems such as Cd1-xMnxSe, Cd1-xMnxTe, and Cd1-xMnxS are included in terms of clusters. Within the framework of the static approximation to the FIM, the spin-flip Raman scattering spectrum and the binding energy of BMPs are calculated. The theoretical results are compared with available experimental data.Keywords
