Fe contribution to the magnetic anisotropy of -ordered FePt thin films studied by angle-dependent x-ray magnetic circular dichroism
Goro Shibata, Keisuke Ikeda, Takeshi Seki +9
Among magnetic thin films with perpendicular magnetic anisotropy (PMA), -ordered FePt has attracted significant attention because of its exceptionally strong PMA. However, th…
