Abstract
We investigated the dynamics of free and bound excitonic magnetic polarons in Cd1-xMnxTe (x=0.03) single crystals by time-resolved photoluminescence e xperiments. We found that the magnetic polarons formed from free excitons a re more stable than those formed from bound excitons. As a consequence, the peal; energies of the optical emissions of free excitons and donor-bound e xcitons cross in the time-resolved photoluminescence spectra. Furthermore, we observed that nonmagnetic localization is not required to form free magn etic polarons.
