Abstract
The magnetocrystalline and magnetoelastic anisotropy energies of bcc ( 110) thin films and superlattices are predicted from group theory and calculated within the framework of an extended pair model. The calcula tion shows the magnetocrystalline and magnetoelastic anisotropy energy per atom in a monolayer to be twice that of a surface layer and that the [001] axis is never expected to be an easy axis of a surface, inte rface or monolayer. Contrary to the magnetocrystalline anisotropy, the magneto-elastic anisotropy is never expected to be larger at the surf ace compared with the volume in this model.
