Room temperature photoreflectance spectroscopy was used to investigate Cd1-xMnxTe/CdTe quantum structures grown by MBE technique. The system of four quantum wells of x = 0.28 with different thicknesses was under study first. The obtained spectrum showed a series of resonances which are attributed to the intersubband transitions. The second group of quantum structures were CdTe/Cd1-xMnxTe MQW. The samples were δ-doped in the middle of the wells by using indium. Transitions related to heavy holes in δ-doped wells were found to occur at different energies thaqn those in undoped wells. The influence of the strains on (CdMn)Te/CdTe quantum stryctures has been taken into account.
