Abstract
We investigate the indirect exchange interaction between localized moments via conduction bands. The origin of the exchange is assumed to be the Anderson s-f mixing mechanism appropriate to anomalous rare earth and light actinide systems. The conduction states originate from s-orbitals in a CsCl structure. Hubbard correlation in Hartree-Fock approximation is included. We perform calculations of the coupling constants between localised moments and obtain a characteristic relationship between the conduction electrons density of states and the magnetic transition temperatureFile in questo prodotto:
