摘要：

The magnetic properties of monoatomic Co wires supported on the Pd(110) substrate have been studied using a self-consistent spd-tight-binding model with parameters fitted to ab initio tight-binding linear muffin-tin orbital results for the ideal Co monolayer deposited on the same substrate. The geometrical structure of the system is based on recent scanning tunneling microscopy experiments for Cu wires supported on Pd(110). Two possible magnetic configurations have been considered, one with parallel (P) magnetic coupling between adjacent wires and the other with antiparallel (AP) coupling. Results are reported for the local magnetic moments and spin-polarized densities of states, magnetic coupling between wires as a function of the interwire distance and wire-substrate magnetic interaction.
