Abstract
Magnetoreflectance from GaAs:Mn was measured in the free exciton range for B less than or equal to 5 T and T = 2.0 K. Combining optical resu lts with magnetization data the value for tile exchange parameter N-0 alpha-N-0 beta = -(2.3+/-0.6) eV was obtained. Assuming that N-0 alpha approximate to +0.2 eV, the ferromagnetic p-d exchange interaction wa s found with tile magnitude N-0 beta approximate to +2.5 eV.
