Abstract
An extensive study of the magnetic moment and of the magnetic anisotropy
of a Co monolayer on a Cu(100) substrate capped by an additional
3d, 4d, or 5d monolayer is presented in terms of first-principles
calculations. While for the magnetic moment of the Co and the cap
layer systematic trends can be traced that seem to be consistent
with the Stoner model, the dependence of the magnetic anisotropy
energy on the type of overlayer is found to be less straightforward.
However, in some selected cases a correlation of the magnetic anisotropy
with the specific features in the electronic structure of the Co
and the cap layer can be pinpointed.
