Abstract
We extend the original single-site spin flip calculation of Korringa to multisite scattering. We consider both one-electron and many-body cases, the latter occurring when one allows for Coulomb exchange scattering between conduction electrons, driven by applied fields against impurities, and those electrons which are screening the impurity at a given instant. Our results show that there are more spin couplings in a dilute magnetic metal than the Ruderman Kittel and Dzyaloshinsky-Moriya interactions. Which appear appears to be a matter of experimental circumstance.
