FePt/B{sub 4}C multilayer composite films have been prepared by magnetron sputtering and subsequent annealing in vacuum. It was found that the B{sub 4}C layers effectively serve as spacers to separate the FePt layers, enhancing (001) orientation of FePt alloy. Our results show that highly (001) oriented [Fe{sub 45}Pt{sub 55}(8 nm)/B{sub 4}C (4 nm)]{sub 3} film with satisfactory perpendicular coercivity (4.75 kOe) has significant potential as a perpendicular recording medium.
