  • Equiatomic CoPt and FePt alloy films with the L10-ordered structure have been attractive as ultrahigh-density magnetic recording media. The vacancy formation energies of some intermetallics with L10-ordered structure were calculated by Miedema′s theory. The types of structural vacancy in the intermetallics were discussed. The Ni vacancy is easy formed in FeNi. The type of structural vacancy in FePt and FePd is the Fe vacancy. The Co vacancy is easy formed in CoPt. The Ni vacancy is easy formed in NiPt. The Pt vacancy is easy formed in MnPt. The type of structural vacancy in MnNi is the Ni vacancy. The Mn vacancy is easy formed in MnPd and MnHg. The Rh vacancy is easy formed in MnRh. This research is provided the reference in researching ultrahigh-density magnetic recording films.
