Abstract:
(FexPt1-x)100-yCuy(x=0.46—0.56,y=0,0.04,0.12) thin films with a fixed thickness of 50nm have been prepared by magnetron sputtering. The atomic ratio of Fe to Pt atoms was accurately controlled by DC co-sputtering. The ordering parameter of the L10 phase is not enhanced for the films with x〉0.52. On the contrary, the ordering process is improved by the addition of Cu for the Pt-rich or stoichiometric thin films. In order to get the ordering of FePt films at a low annealing temperature, the lower the Fe content, the more addition of Cu is needed. It is found that the L10 phase can be obtained after annealing at 350℃ for 20 min only for films with the ratio of the (FeCu)/Pt in the range of 1.1—1.2.
