The possibility of excitons bound to magnetic impurities in a two-dimensional system quantized by a strong magnetic field is considered. We show that the Landau quantization leads to dramatic changes in the structure of these bound excitons. Such changes are due primarily to a lower symmetry, which lifts the selection rules in the hybridization integrals, and in turn leads to a threshold van Hove singularity of the density of states in a two-dimensional system. Hence, a bound exciton with zero angular momentum, m = 0, is captured by a spin selective potential of the deep impurity levels.
