Abstract

Growth-induced uniaxial magnetic anisotropy of Co/Cu(100) films were investigated using surface magneto-optic Kerr effect and scanning tunneling microscopy (STM). We found that the Co films off-grown at 230 K show an in-plane uniaxial magnetic anisotropy with the easy magnetization axis perpendicular to the growth incident plane. STM measurements show that the low temperature grown Co film consists of smaller islands without obvious anisotropic roughness or elongated islands. This result implies that the dipolar interaction does not dominate the uniaxial magnetic anisotropy. The CO absorption experiment further suggests that the uniaxial magnetic anisotropy originates from the magnetocrystalline step anisotropy of the Co film surface.
