In this work we calculate in a quantitative way the temperature dependence of localized and itinerant magnetizations of the PrCo 2 intermetallic compound. In the model we start from a two-sublattice Hamiltonian which includes itinerant electrons, localized states and the crystal-field effects on the 4f levels of rare-earth ion. In the calculation we used the functional integral method to treat the electron-electron interaction and the molecular field approximation to deal with the indirect interaction between localized states.
