Abstract
The concentration dependence of the Curie constant in the magnetic susceptibility of impurities of transition elements in a nonmagnetic matrix is considered for the case where the energy level of an impurity electron falls into the conduction band and hybridized states arise. As a result of an analysis of the new experimental data on the magnetic susceptibility of the iron impurity in crystals of mercury selenide, a substantiation of the earlier proposed simple formula that describes the linear dependence of the Curie constant on the concentration of impurities with allowance for the hybridization of states is given. The application of this formula to the description of the temperature dependence of the magnetic susceptibility of the cobalt impurities allowed us, on the basis of the formulated ideas about the arrangement of the energy levels of d electrons and of the available data on the Hall concentration of electrons, to find the effective spin of the hybridized electronic states at the impurity cobalt and the resonance value of the concentration of donor electrons.
