A multilayered deposition structure was developed for fabricating FePt:B 2O 3 films. We successfully obtained nanostructured FePt:B 2O 3 films with FePt grains aligned perpendicular to film plane by postannealing the as-deposited multilayers at 550°C for 30 min. It was found that development of (001) texture depends strongly on the total film thickness, initial B 2O 3 layer thickness, and Fe concentration. Nearly perfect (001) orientation of FePt-ordered grains can be obtained in the films with small total film thickness, large initial B 2O 3 layer thickness, and slightly higher Fe concentration. Our results show that highly (001) oriented films with ordered fct phase have significant potential as perpendicular media for extremely high-density recording.
