A Tight-binding Study of Surface Magnetic Anisotropy of the Co (0001) and Its Perturbation by Cu and CO.

Original language description

Recent experiments show that on rather thick Co films, deposition of Cu or adsorption of CO or C can switch the magnetization direction along the surface normal. We present semi-empirical self-consistent tight-binding calculations for a semi-infinite hcpCo(0001) crystal. It appears that the magnetic anisotropy-energy contribution from the surface layer prefers the in-plane alignment of magnetic moments. Various surface perturbations (Cu deposition or CO adsorption, artificial suppression of surface magnetization), however, reduce this contribution considerably or even change the sign of the electronic part of the magnetic anisotropy-energy, making thus conditions for perpendicular magnetization more favourable.
