The electronic and magnetic properties of a coherent modulated structure consisting of three atomic layers each of Cu and Ni perpendicular to (111) were determined from ab initio self-consistent spin-polarized energy-band calculations. We predict a susbtantial reduction in spin magnetization and contact hyperfine fields H/sub n/ at the Ni layers (in contrast with enhancements reported earlier from ferromagnetic resonance measurements), charge (0.1e/sup -/) and spin (approx.0.01..mu../sub B/) transfer to the Cu sites, and large H/sub n/ at the Cu nuclei.
