Interaction of Anderson impurities with high orbital angular momenta: Non-RKKY behavior and instability of Kondo lattice

Abstract

The hybridization-induced interaction of Anderson impurities with orbital angular momentum l is revisited. At short distances R<Rc∝(l+1)/kF the interaction has antiferromagnetic sign and decays as (Rc/R)4l. At larger distances R>Rc the RKKY-like oscillatory interaction sets in. As l increases, the system will sooner or later enter the “short-distance” domain, where the intersite magnetic interaction dominates over the screening processes. This means that, contrary to previous expectations, the nonmagnetic state of the Anderson lattice is unstable at l→∞.
