The Brillouin light-scattering measurements and magneto-optic Kerr effect were performed on a 4°-miscut Si(111)/Cu/Au(2ML)/Co(5ML)/Au system. The correlation between slanted angle and magnetic anisotropy of the ultrathin Co layer was discussed. It was found that the easy axis orientation was neither in-plane nor perpendicular with respect to the sample surface. The direction of incline was also found to be correlated with the step direction. The results show that the steps in the 4°-miscut Si(111) substrate were the cause of the slanted magnetic anisotropy axis.
