We have explored the interlayer diffusion effect of Ge/FePt, GePt/FePt bilayer on the formation of ordered L1(0) FePt phase. In Ge/FePt bilayer, the Ge3Pt2 compound was formed during post annealing at 400 degrees C for 1.0 h. Diffusion between Ge and FePt layer suppres the formation of ordered L1(0) FePt phase. With Ge2Pt3 underlayer, the FePt film was ordered at 400 degrees C and the in-plane coercivity was 9.3 kOe. The ordering temperature was reduced about 50 degrees C compared to the single layer FePt film. (C) 2006 Elsevier B. V. All rights reserved.
