Assembly of high-anisotropy L10 FePt nanocomposite films

Assembly of high-anisotropy L10 FePt nanocomposite films

In this paper we report results on the synthesis and magnetic properties of L10 FePt nanocomposite fi lms. Three fabrication methods have been developed to produce high-anisptropy FePt fi lms: non-epitaxial growth of (0 0 1)-oriented FePt:X (X=Ag, C) composite fi lms that might be used for perpendicular media; monodispersed FePt(CFx) core–shell nanocluster-assembled fi lms grown with a gas-aggr...

Modulation of preferred orientation and easy axis of magnetic anisotropy in L10 FePt films with Cu buffer layers

The crystallographic orientation and easy axis of magnetic anisotropy in L10 FePt films were successfully modulated with Cu buffer layers. The FePt film directly grown on the Cr90Mo10 underlayer showed a (001) preferred orientation with out-of-plane magnetic anisotropy. As the Cu buffer layer thickness was z4 nm, the FePt films showed a (110) preferred orientation with in-plane magnetic anisotr...

Controlling the crystallographic orientation and easy axis of magnetic anisotropy in L10 FePt films with Cu additive

By co-sputtering Cu and FePt onto Cr90Mo10 underlayers, the preferred orientation and easy axis of magnetic anisotropy of FePt films were successfully changed from the perpendicular to the in-plane direction. The pure FePt film grown on the Cr90Mo10 underlayer showed a (001) preferred orientation with out-of-plane magnetic anisotropy. As 20 and 40 vol.% Cu were doped, the FePt films showed a (2...
