Abstract

In this paper we briefly review some calculations of the dynamic magnetic susceptibility of impurities in metals. We limit ourselves to the best known limits, i.e. the case of a spin-1/2 Kondo impurity (section II) and the mixed-valence impurity with orbital degeneracy (section III). In the mixed-valence regime we summarize the main results for Ce and Tm impurities and discuss the validity of the approximation by comparing with the exact Bethe-ansatz solution for the ground-state.
