Magnetic, optical and transport properties of heterostructures based on diluted magnetic semiconductors (DMS) are determined by coupled systems of magnetic ions, lattice (the phonon system) and free carriers. The system of free carriers (its concentration, temperature and spin polarization) is of great importance for static characteristics and dynamical response of DMS materials as it modifies strongly efficiency of energy- and spin transfer between the systems of DMS heterostructures.

This talk will give an overview of our recent experiments on II-VI DMS quantum wells with a type-I band alignment (ZnMnSe/ZnBeSe and CdMnTe/CdMgTe) and with a type-II band alignment (ZnMnSe/BeMnTe) [1-6].
