High-quality L10 ordered 20nm-thick FePd epitaxial thin films with a large perpendicular magnetic anisotropy were fabricated using a SrTiO3 substrate. The uniaxial crystalline magnetic anisotropy constant Ku evaluated for the films annealed above 500°C was 14 Merg/cm3. A very low effective damping constant, αeff=0.007, was observed for FePd thin films annealed at 500°C. This value is smaller than that of other Fe-based ordered alloys with a large perpendicular magnetic anisotropy.
