摘要：

Calculating the exact mean-field free energy from a Heisenberg-like Hamiltonian we determine the magnetic phase diagram for cubic-based praseodymium compounds with a Gamma(3) doublet ground state and a Gamma(4) triplet first-excited state, We find lines of first- and second-order phase transitions, separated by a tricritical point. We also calculate the temperature dependence of the magnetic-order parameter.
