Abstract

AbstractA detailed theoretical analysis is made of the hyperfine properties of metallic copper in the framework of the orthogonalized plane‐wave method and pseudopotential formalism using a reliable model for the Fermi surface of copper. The direct and exchange core polarization (ECP) contributions to the conduction electron spin density are evaluated and the role of the ECP contribution is discussed. The exchange and lattice enhancement effects on the Knight shift and the spin‐lattice relaxation time are taken into account accurately. The agreement between the theoretical results and the available experimental data is quite satisfactory.
