摘要：

Results of infrared reflectivity (in the phonon and plasma edge spectral regions) and magnetic susceptibility investigations performed on Hg1-xCoxSe samples corresponding to a wide range of the crystal compositions (0 < x < 0.05) are presented and discussed. The evidence of an acceptor character of Co impurity is shown. Antiferromagnetic interactions between Co2+ are confirmed, effective exchange integral is estimated to be J(d-d)/k(B) = (-61.3 +/- 6.7) K.
