Abstract: Fe/Pt multilayers and FePt thin films are prepared by DC magnetron sputtering.The as-prepared samples are subjected to vacuum annealing at temperature in the range of 300～550℃.The multilayered structure is an effective approach for reducing the ordering temperature of FePt.The ordering parameter S is evaluated to be 0.6,and the coercivity is evaluated to be 501kA/m in ［Fe(1.5nm)/Pt(1.5nm)13 multilayers at 350℃ annealing temperature.This appreciable reduction is correlated with rapid diffusion at the interface of Fe/Pt.

Key words: L10-FePt order phase, magnetron sputtering, ordering parameter, Fe/Pt multilayer
