Descripción: A simple magnetic model for <math>PrCu_5\,\!</math> is proposed. The two basic features are: 1) a simplified singlet-triplet crystal field splitting extracted from the nine level scheme <math>(J = 4 for Pr^{+3})\,\!</math> of the actual crystal field levels given in the literature and 2) a molecular field approximation of the exchange interaction between the <math>Pr^{+3}\,\!</math> ions. A magnetic state equation is derived and a best fitting analysis of the magnetic susceptibility given in the literature is performed. We also discuss the combined role of exchange and crystal field on the onset of magnetic order.
