摘要：

We fabricated the FePt film on thermal oxidized Si substrate by rapid thermal annealing (RTA), and investigated the order parameter and the orientation parameter as a function of annealing temperature. We also observed grains by a transmision electron microscope (TEM). The joining of the grains begins at between 300degreesC and 400degreesC and this is the threshold for obtaining highly (001) oriented FePt films, We also clarify the difference in the magnetization and the structure between the films annealed from Pt/Fe (Fe-first) and from Fe/Pt (Pt-first) multilayers as the starting material,;. The film annealed from the Fe-first multilayers has the perpendicular magnetization showing higher (001) orientation and magnetic anisotropy than the film annealed from the Pt-first multilayers.
