Ultrathin Ni films are grown on stepped Cu(001) in 0 degree sign -10 degree sign range of the vicinal angle. Spin-reorientation transition (SRT) of these films is studied in situ using surface magneto-optical Kerr effect. The SRT thickness is invariant up to 7 degree sign vicinal angle. Adsorption of submonolayer Co at the Ni step edges, however, increases significantly the SRT thickness. The results are quantitatively reproduced by a simple phenomenological model considering the presence of step-induced anisotropy. (c) 2000 The American Physical Society.
