摘要：

A 15-nm-thick Pt buffer layer was deposited on a glass slide at temperature T(s)(Pt(buf)) ranging from 30 to 300-degrees-C by e-gun evaporation. Following the cooling in vacuum to ambient temperature, Co and Pt layers have been alternately deposited on it. Very large perpendicular anisotropy and coercivity have been obtained at T(s)(Pt(buf)) higher than 200-degrees-C. The (111) preferred orientation of the Co/Pt multilayer as well as the Pt buffer layer became more pronounced with elevating T(s)(Pt(buf)), to which the enhancement of perpendicular anisotropy with elevating T(s)(Pt(buf)) might be ascribable.
