Surface and ultrathin-film anisotropies in epitaxial fcc Fe thin films grown on room temperature Cu(100) single crystals in an ultrahigh vacuum has been investigated, in situ, by the combined surface magneto-optical Kerr effects (SMOKE). When the applied field is perpendicular to the film surface, rotation processes occurring between out-of-plane and in-plane directions suggest the presence of an induced uniaxial (canted) anisotropy directed out of the plane of the film. This hypothesis is tested with a simple coherent rotation model.
