A novel method to fabricate FePt-ordered alloy thin films with (0 0 1) preferential orientation from Pt/Fe bi-layered films has been developed. It is able to omit post-annealing with a furnace, and the whole process can be conducted in a chamber without exposing samples to air. In this method, the inter-diffusion and the hetero-epitaxial relation between Fe and Pt are key factors to attain an FePt-ordered alloy thin film with (0 0 1) preferential orientation. An FePt-ordered alloy thin film with (0 0 1) preferential orientation fabricated from Pt[3 nm]/Fe[3 nm] bi-layer employing this method exhibited a relatively large coercivity of 5.6 kOe and high squareness ratio of 0.94 on perpendicular magnetization property. This novel method has a potential to fabricate FePt-based perpendicular magnetic recording media more easily than several conventional methods.
