- Description
- We present a simple magnetic model for <math>PrAl_{3}\,\!</math>. The effects of crystal field are treated using a reduced set of levels and the corresponding wave functions are extracted from the actual crystal field levels of <math>Pr^{+3}\,\!</math> in a hexagonal symmetry. The exchange between <math>4f\,\!</math>- and conduction electrons are dealt within a molecular field approximation. An analytical magnetic state equation is derived and the magnetic behaviour discussed. The parameters of the model are estimated from a fitting of the inverse susceptibility of <math>PrAl_{3}\,\!</math> given in the literature.
