Abstract
The magnetic interactions in the metallic phase of the copper oxides and associated dynamical susceptibility are calculated within a Fermi liquid scheme in which the Cu electrons are nearly localized and the oxygen bandwidth assumes physical values. Both superexchange ( J S) and RKKY interactions ( J R) emerge from our diagrammatic formalism on a similar footing. With increasing carrier concentration, J S decreases rapidly, while J R abruptly increases from zero. These self consistently determined interactions and “renormalized” bandstructure lead to an enhanced stability of the Fermi liquid phase.
