A MODEL FOR LOCAL MAGNETIC MOMENT AND THE VALENCE OF f ELECTRONS IN METALS

In this paper we suggest a model in which f electrons are bound in a narrow band near Fermi level, s-p-d electrons free and hybridization between them is considered. Numerical results show that the local magnetic moment of the f electron possesses certain stability under varying pressures. A phase diagram is plotted. The case of intermediate valence is discussed qualitatively.
