Abstract

Two series of FePt/[Co/Pt]N (FPCP-N) and FePt/[Co/Ni]N (FPCN-N) exchange coupled composite (ECC) films were prepared and studied. Well isolated island-like grains with an average grain size of about 20nm are obtained. Both FePt hard layer and Co based soft multilayer are of perpendicular anisotropy. Large reduction of the switching field is observed when the Co based multilayer is deposited on the top of FePt films. When the thickness of Co based multilayers increase, thermal stability of the composites decreases slightly in both two series. Therefore, low switching field and high thermal stability are both obtained in these perpendicular ECC films.
