摘要：

The magnetization of the Ni(110) surface is explored as a function of the CO coverage by means of periodic slab calculations within density-functional theory. The in-plane inspection of the spin density corresponding to the surface layer exhibits a CO-induced decrease in the Ni-atom magnetic moments that is limited to the atoms directly involved in the chemisorption bond. This decrease is due to interactions between the metal states and the CO orbitals that increase the population of the spin-down metal states within the outermost layer and decrease that of the corresponding spin-up ones.
