Interface structures in FePt/Fe3Pt hard-soft exchange-coupled magnetic nanocomposites
Abstract
Interface structures in FePt/Fe3Pt hard-soft exchange-coupled magnetic nanocomposites were investigated. Annealing the composite under reducing atmosphere at 650 and 700°C induced magnetically hard FePt phase and magnetically soft Fe3Pt phase. The structural characterization for the FePt based composites were studied using high-resolution transmission electron microscopy.
