Abstract
Time-resolved photoluminescence (PL) and optical pump–probe experiments were carried out in Cd 1− x Mn x Te/ZnTe multiple quantum wells to study the dynamics of the exciton 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. On the contrary, the high-energy positive peak indicates the enhancement of the density of states due to correlation effects.
