Multilayer films consisting of hard and soft magnetic materials have been studied to investigate the possibilities for anisotropic nanocomposite magnet and high-density perpendicular media. Although rare-earth based magnetic materials are commonly employed as the hard magnetic material, L10-ordered alloys are also considered to be the candidate for the hard magnetic material. In the present study, epitaxial bi-layer films consisting of FePt or FePd and Co layers are prepared on MgO(001) single-crystal substrates to investigate the possibility in forming well controlled hard/soft multilayer magnetic thin films. The FePt layer in Co/FePt bi-layer film formed on MgO(001) is found to be consisting of only L10(001) variant, whereas FePt single-layer is consisting of L10(100), (010) variants in addition to the L10(001) variant. The structure of L10 ordered layer in bi-layer film has been shown to vary delicately depending on the stacking sequence. |
