Annotation

The paramagnetic susceptibility of rare-earth metal compounds, such as Er$_{1-x}$Ho$_x$Rh$_4$B$_4$, is studied in terms of the microscopic theory of complex compounds. It is shown that the inverse statistical susceptibility of these systems obeys the Curie-Weiss law, with the Curie temperature being determined by the exchange interaction in the self-consistent approximation. The obtained results are compared with experimental data.
