The magnetic susceptibility of GeS₂-Ga₂S₃-MnS glasses is investigated in the temperature range from 6 to 300 K. The nonlinear temperature dependence of the reciprocal paramagnetic susceptibility is quantitatively described in terms of the previously proposed model for low-temperature paramagnetism of glasses. The concept underlying this model implies that vitreous materials exhibit a fluctuation nature. The model is improved and applied to analysis of the obtained experimental data. The numerical characteristics of manganese distribution over the glass network positions differing in composition of the second coordination sphere are determined.
