Abstract

Photoluminescence in diluted magnetic semiconductors Cd1-xCoxSe(x = 0.012) and Cd1-xMnxSe(x = 0.10, 0.25) has been measured under magnetic fields up to 27 T at 4.2 K in the presence of hydrostatic pressures up to 2GPa. The pressure dependence of the giant Zeeman shift of the A-exciton in Cd1-xCoxSe(x = 0.012) shows that the ferromagnetic exchange field due to Co2+ ions increases with pressure at a rate of 6-7%/GPa, which is an order of magnitude greater than the compressibility of the lattice constant. In Cd1-xMnxSe, on the other hand, the exchange field due to Mn2+ ions is insensitive to pressure for x= 0.10 and rather decreases with pressure for x = 0.25.
