The dependence of the exchange field on the paramagnetic impurity concentration in dilute metals is investigated. The consideration of the difference in the occupation probability of sites at different coordination spheres results in a variety of concentration dependences of the exchange field instead of a linear dependence. The concrete type of this dependence is determined by the conduction electron density. Numerical calculations are made of the paramagnetic Curie temperature change with dilution for a simple cubic crystal.
