We reported the fabrication of (001)-textured FePt-TiO2 nanocomposite thin films composed of isolated grains of size of 5.3 +/- 1.1 nm. Anisotropy graded FePt-TiO2 thin films with hard layer thickness of 10 nm and soft layer thickness ranging from 0 to 8 nm were also prepared by cosputtering FePt and TiO2 at different substrate temperature. An exchange-coupled composite effect was demonstrated at a soft layer thickness of more than 3 nm.
