Kondo effect in disordered systems

We consider a system of dilute magnetic impurities placed in a disordered metal, and examine the modifications of the Kondo temperature Tₖ due to the presence of disorder. Our calculations, based on a slave-boson approach, show that the probability distribution P(TK) for Kondo temperatures can be related to the local-density-of-states fluctuations induced by localization effects. The resulting P(TK) is shown to be sufficiently singular to induce diverging magnetic susceptibility {χ} as T{→}0, a non-Fermi-liquid behavior.
