Abstract

We calculate the dynamic susceptibility χ(ω) in the Anderson impurity model, using a 1/Nf expansion, where Nf is the degeneracy of the f-level, For Nf→∞ the Shiba Fermi liquid relation is satisfied. In this limit Im χ(ω)/ω has a very steep rise at ω=TK, the Kondo temperature. An interpretation for this rise is given. Crystal-field and spin-orbit splittings have also been included.
