| Abstract: | FePt multilayer composite films with and without B4C interlayer have been prepared by magnetron sputtering, respectively, and subsequent annealing in vacuum. It was found that the B4C layers effectively serve as spacers to separate the FePt layers, enhancing (0 0 1) orientation of FePt alloy. Our results show that highly (0 0 1) oriented FePt/B4C films have significant potential as perpendicular recording media. |
