Using a Fermi-liquid formalism in which the Cu {ital d} electrons are quasilocalized, we calculate the NMR relaxation for the Cu and O sites, the temperature-dependent magnetic susceptibility, and the neutron-scattering cross section. Our microscopic calculations of the dynamical susceptibility help to decouple narrow-band phenomena from spin-fluctuation effects. The former lead to a low (coherence) energy scale and considerable structure in the Lindhard function. The latter help to enhance these effects.
