摘要
We have studied the chemical ordering of granular films (CoPt)(1-x)Ag-x/SiO2 with the concentration x=2-6 at. %. It was found that the additive Ag efficiently promotes the ordering process, reducing the ordering temperature by 100 degrees C compared with that of without Ag. The additive Ag also stimulates nearly perfect (001) orientation of the CoPt-ordered grains in the films with a thickness of less than 50 nm, resulting in a large perpendicular magnetic anisotropy.
