In the present study, we succeeded in accelerating the L10ordering transition of FePt thin films by employing amorphous Ni–Al as underlayers. The coercivity Hc=5kOe and ordering parameter S=0.67 of FePt thin films deposited on a Ni–Al underlayer with a thickness of ∼5nm after 380°C annealing for 30min are significantly higher than those Hc=0.4kOe and S=0.35 of the films without the Ni–Al underlayer. The L10ordering process of and the coercivity of FePt thin films can be significantly tuned by varying the thickness of the Ni–Al underlayer.
