Abstract
The magnetization of Cd1-xMnxTe can be reduced by the Mn2+ magnetic re sonance. The decrease of the magnetization affects all the ''edge'' em issions of the material studied, which shift towards higher energies. It also affects the relative efficiencies of the free exciton (FE) and the acceptor bound exciton (ABE) emissions. The latter decays mostly nonradiatively, which is due to a competing Auger transition. The larg e Auger recombination rate of the ABE is directly confirmed by the pre sent optically detected magnetic resonance (ODMR) investigations.
