Interaction of Anderson impurities with high orbital angular momenta : non-RKKY behavior and instability of Kondo lattice
Ioselevich A.S.
PACS: 75.20.Hr, 75.30.Mb
Hybridization-induced interaction of Anderson impurities with orbital angular momentum I is revisited. At short distances R < Rc oc (I + l)/kp the interaction has antiferromagnetic sign and decays as (Яс/Я)4'. At larger distances R > Rc the RKKY-like oscillating interaction sets in. If I increases, then, sooner or later, the system occurs in the "short distance" domain, where the intersite magnetic interaction dominates over the screening processes. It means that, contrary to previous expectations, the nonmagnetic state of Anderson lattice is unstable at i -> oo
