Magnetic re-entrance in intermediate valence compounds

We explore the possibility of magnetic re-entrance in intermediate valence compounds. Using a simplified Anderson-Lattice model we obtain the pressure-temperature magnetic phase diagram. This diagram shows that for some value of the microscopic parameters the temperature induced two transitions (non-magnetic to magnetically ordered to paramagnetic).We calculate the magnetization and the average occupation number of the localized state. Estimations of the observability of the effect in systems like CeAl₂ are made.
