Abstract
The anisotropy of fee (111) Fe/Ni and Fe/Ni/Fe layers is investigated. The films exhibit an oscillating behavior of the preferential magneti zation direction depending on whether the surface layer is Ni or Fe. A nisotropy fields are obtained from polar and perpendicular Kerr hyster esis loops and yield a comparatively small perpendicular Fe/Ni interfa ce anisotropy of about 8.15 mJ/m(2). The real-space origin of the inte rface anisotropy is the interlayer hybridization of the yz, zx, and z( 2) orbitals.
