Abstract
Photoluminescence (PL) measurements in CdTe/Cd1-xMnx Te (x=0. 24) single quantum well (SQW) structure with different quantum well (QW) widths and bulk Cd1-xMnxTe (x=0. 15) under high hydrostatic pressures up to 2. 68 GPa and DC magnetic fields up to 30 T are reported. We analyze the Zeeman shift of the band-edge exciton PL peaks, taking into account a linear magnetization term, and obtain pressure dependence of spin exchange parameters. Negative pressure dependence of the p-d hybridization is found for the barrier of the SQW structure and the bulk sample. A possibility that the hybridization is weakened due to the pressure induced relaxation of the distortion around Te atoms is proposed.
