The surface magneto-optical Kerr effect is used in conjunction with structural and growth-mode characterizations to survey the surface magnetic anisotropy behavior of three metastable Fe-film systems: Fe on Cu(100), Ru(0001), and Pd(100). Each system grows epitaxially in the ultrathin regime and exhibits the universal behavior of perpendicular ferromagnetic spin orientations below a critical thickness of 6 monolayers or less. The systems differ, however, in their monolayer-dosage magnetic properties due to interdiffusion and hybridization at the interface. Fe/Pd(100) exhibits submonolayer magnetism, while <2-monolayers Fe/Ru(0001) lacks a ferromagnetic signature, in accord with expectations based on moment formation in dilute Fe alloys. 41 refs., 4 figs.
