Structurally gradient layered A1/L1{sub 0} films are obtained by heat treatment of magnetron sputter deposited FePt(20 nm)/CoPt(x nm) bilayers where x=0-120 nm. The magnetic properties can be tuned by adjustment of the layer thicknesses and taking advantage of the different heat-treatment temperatures required for the ordering of the L1{sub 0} phase between FePt and CoPt.
