概要

The anisotropy energies of (Ill) and (001) oriented Ag/Fe and Au/Fe multilayers are ob-tained by a first-principle calculation to inxzestigate the orientational dependence of the magneticanisotropy. All systerns show perpendicular anisotropy in good agreement with experiments. Inthe case of Ag/Fe rnultilayers, the anisotorpy energy of the (001) oriented multilayer is larger thanthat of the (111) rnultilayer. In contrast to Ag/Fe, Au/Fe(Ill) rnuItiJayer exhibits a strongerperpendicular anisotropy than the (001) oriented system. In all systems, a large nuinority-spinLDOS of m : 2 character of Fe near the Fermi energy cotrld be the origin of perpendicularmagnetic anisotropy.
