Time-resolved photoluminescence has been studied in molecular beam epitaxy grown Cd1-xMnxTe/Cd1-yMgyTe and CdTe/Cd1-xMnxTe single and multiple quantum wells. The excitonic properties were investigated at several temperatures and magnetic fields. The dynamics of the exciton magnetic polaron are greatly influenced by the quantum confinement of the excitons in the single quantum wells. The formation of a spin superlattice structure was realized in Cd0.95Mn0.05Te/Cd0.95Mg0.05Te multi-quantum wells under an external magnetic field.
