Abstract
The theory of Moriya is extended to include electron-electron interaction potentials with a strong momentum dependence. This extension is based on recent theoretical studies of the electron-gas response. It is shown that the observed enhancement of the Korringa relation in alkali metals can be attributed almost entirely to electron-electron interactions described by an effective interaction potential derived from the pair-correlation function for a low-density electron gas.Keywords
