    Time-resolved photoluminescence (PL) and optical pump-probe experiments were carried out in Cd1-xMnxTe/ZnTe multiple quantum wells to study the dynamics of the excitonic magnetic polaron in this material. In the pump-probe data, three signals were detected. The main signal is negative and monitors the energy relaxation of the excitons created by the pump pulse. The other two pump-probe signals are positive and their intensity grows while the excitons created by the pump pulse recombine. The low-energy positive pump-probe signal is found to track the average Mn spin polarization in the sample. Instead, the high-energy positive peak indicates the enhancement of the density of states due to correlation effects.
