Based on interfacial manipulation of the MgO single crystal substrate and non-magnetic AlN compound, a L10-FePt perpendicular ultrathin film with the structure of MgO/FePt-AlN/Ta was designed, prepared, and investigated. The film is comprised of L10-FePt "magnetic islands," which exhibits a perpendicular magnetic anisotropy (PMA), tunable coercivity (H C), and interparticle exchange coupling (IEC). The MgO substrate promotes PMA of the film because of interfacial control of the FePt lattice orientation. The AlN compound is doped to increase the difference of surface energy between FePt layer and MgO substrate and to suppress the growth of FePt grains, which takes control of island growth mode of FePt atoms. The AlN compound also acts as isolator of L10-FePt islands to pin the sites of FePt domains, resulting in the tunability of H C and IEC of the films.
