The dominant mechanism responsible for the optical detection of the Mn^{2+} magnetic resonance in Cd_{1-x}Mn_{x}Te (x = 0.095, 0.007) is explained. By either change of the external magnetic field or by setting the conditions for the Mn^{2+} magnetic resonance, we could change the relative efficiencies of the two competing excitonic recombination processes. By lowering magnetization at the magnetic resonance, recombination via the acceptor bound exciton channel, which is mainly nonradiative, is enhanced. Then, a large up to 50% decrease in the total photoluminescence efficiency was observed in the optically detected magnetic resonance experiment. Such observation allows for verification of the large efficiency of the Auger-type transition responsible for the nonradiative decay of the acceptor bound exciton.
