Popis:	A 15-nm-thick Pt buffer layer was deposited on a glass slide at temperature T s(Ptbuf) ranging from 30 to 300°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(Ptbuf) higher than 200°C. The (111) preferred orientation of the Co/Pt multilayer as well as the Pt buffer layer became more pronounced with elevating T s(Ptbuf), to which the enhancement of perpendicular anisotropy with elevating T s(Ptbuf) might be ascribable.
