Kondo spin compensated state

Edelstein (1968, 1970) has adopted the Coqblin-Blandin model for cerium but with an emphasis on the effect of spin compensation. This point of view was that the decrease or loss of the magnetic moment in a-Ce and the slightly decreased moments in y- and /3-Ce (based on Lock s data) was due to the antiferromagnetic polarization of conduction electrons around the 4f virtual state. Edelstein supported this idea in part by noting an apparent T dependence of the magnetic susceptibility of mixed phase cerium samples above 13 K (Lock, 1957). This temperature dependence had been suggested by Anderson (1967) for the spin compensation contribution to the susceptibility for Kondo alloys. However, subsequent susceptibility measurements of single phase a-Ce (see... 

An analysis similar to that discussed in the text yields a set of foiur spin-compensated Kondo states Pa), I f b), l c), and the spin-orbit split state I f s-o) wifi binding energies bE, dEb, dEc and bEs, respectively. These binding energies are given by the expressions...
