Abstract
A calculation of the temperature and f-level dependence of the static f-electron susceptibility of the periodic Anderson Hamiltonian (PAH) for the cases of one (Nt=1) and two (Nt=2) electrons per atom and in the strongly mixed valent regime is presented. Correlations are included beyond meanfield. Evidence for a tendency towards ferromagnetic order is found for some parameter values in the case Nt=1. For Nt=2, the susceptibility exhibits a peak at finite temperature, a feature typical of many mixed valent compounds, and this peak correlates with the appearance of a pseudo-gap in the f-electron density of states. The theory is correct at high temperature, where the known perturbative results are correctly reproduced.
