Abstract
FePt multilayer composite films with and without B 4C interlayer have been prepared by magnetron sputtering, respectively, and subsequent annealing in vacuum. It was found that the B 4C 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/B 4C films have significant potential as perpendicular recording media.
