Current-induced fast-ordering method (CIFOM) was designed to achieve an ordered L10 -FePt film with small grain size under low energy consumption by applying direct current (DC) in the FePt film. The grain size (∼ 8 nm) of the L10-FePt film prepared by CIFOM method is about one-third of that produced by the post-annealing method (PAM). The fast ordering of the L10 -FePt film by CIFOM is probably attributed to the momentum exchange between the FePt atoms and the conductive electrons. The short ordering time by CIFOM contributes to the smaller grain size of FePt film.
