Abstract

Thermally processed FePt/Fe and FePt/Co multilayers were prepared and the hysteresis loops of the partially textured hard-magnetic materials and its relationship to the nanostructure of the films were investigated. Single layer and multilayer thin films were prepared by magnetron sputtering, and the samples were heat treated by rapid thermal annealing. Results indicated that higher annealing temperature and longer annealing time produced higher coercivities and lowered the magnetization. The magnetic properties depended on the volume fraction of the soft phase.
