Epitaxial PtFe(001) thin films on MgO(001) with perpendicular magnetic anisotropy

Abstract

We report a technique for producing the ordered PtFe intermetallic compound with perpendicular magnetic anisotropy and a preferred c-axis orientation perpendicular to the film plane. PtFe alloys possess high magneto-optic Kerr rotations and magnetizations, suggesting them as likely candidates for magneto-optic and perpendicular magnetic recording.
