Interaction Between Localized States in Metals

Abstract

The theory of localized magnetic states of solute atoms in metals is extended to the case of a pair of neighboring magnetic atoms. It is found that the simplified model based on the idea that the important interaction is the diagonal exchange integral in the localized state, which is exactly soluble in Hartree-Fock theory for isolated ions, is still soluble, and the solutions show both ferromagnetic and antiferromagnetic exchange mechanisms.
