Abstract

The (001) oriented Fe1-xPtx alloy films have been grown on Pt seeding layers on MgO (001) substrates by MBE. At growth temperature of 500 degreesC, rather ordered structures were formed for FePt, FePt2, and FePt3 films, which exhibit large perpendicular magnetic anisotropy and Kerr rotations. In contrast, Fe2Pt and Fe3Pt films were poorly ordered and did not display perpendicular magnetization for similar growth conditions. The optimal growth temperature of the FePt (x = 0.5) alloys occurs at about 500 degreesC, and the surface order-disorder transition occurs above 650 degreesC. We demonstrate that chemical ordering is important for perpendicular magnetic anisotropy and Kerr effects for Fe1-xPtx alloy films, which in turn depend strongly on the alloy composition and growth temperature.
