Abstract

L10-ordered systems are of great interest from both the technological and research point of view since their high magnetocrystalline anisotropy makes them suitable candidates for future high density recording media. FePd and FePt are isostructural alloys that in their ordered phase show very different magnetic behaviour. In this work ultra-thin films of FePd and FePt films have been grown showing very hard magnetic properties. The coercivity of FePd films grown at 700°C reaches values well above 10 kOe much greater than that obtained in FePt films grown in the same conditions.
