We find that the easy axis orientation of the Co layer in the 4°-miscut Si(111)/Cu/Au(2ML)/Co(5ML)/Au system is neither perpendicular nor in plane. Analysis of magneto-optical Kerr effect and Brillouin light scattering measurements for various angles of in-plane applied magnetic field with respect to the miscut direction reveals that easy axis orientation is slightly slanted from the film normal toward the direction of the miscut. Since there is no such slanted magnetic anisotropy axis in films grown on a nonmiscut Si substrate, and since the direction of incline is strongly correlated with the step direction, we conclude that the slanted magnetic anisotropy axis is induced by the steps in 4°-miscut Si(111) substrate.
