摘要

The magnetic' properties of ultrathin Co/Ag/Si(1ll) films were studied by surface magneto-optic Kerr effect. A magnetic phase diagram for binary-metal Co/Ag films deposited on Si(lll) surfaces has been successfully established. The phase diagram can be divided into four regions: nonfcrromagnetic Co-Si compound; low Curie temperature Co film; canted out-of-plane anisotropy; in-plane anisotropy. The ferromagnetic inactive layers at the Co/Si interface are formed due to intermixing of Co and Si; and can be efficiently reduced by the Ag buffer layer. We have demonstrated that the inactive layer thickness is reduced from 2.1 ML for Co/Si(lll) to 1.0 for Co/2.8MLAg/Si(lll), and 0.0 for Co/5.6MLAg/Si(lll).
