Abstract (in Japanese) (See Japanese page) 
(in English) FePt, FePd, CoPt, and CoPd alloy epitaxial films are prepared on MgO single-crystal substrates of (001), (110), and (111) orientations by ultra-high vacuum RF magnetron sputtering. The effects of film material, substrate orientation, and substrate temperature on the film growth, the film structure, and the magnetic properties are investigated. L10 ordered phase formation is observed for FePt and FePd films prepared on all the MgO substrates at elevated temperatures. L10 ordered CoPt epitaxial films are also obtained on MgO(001) and MgO(110) substrates heated at 600 °C. With increasing the substrate temperature, the L10 ordered phase formation is enhanced for these films. The degree of L10 ordering varies depending on the film material. A higher ordering parameter is observed in the order of FePd > FePt > CoPt. On MgO(001) substrates, the L10-FePd films consist of (001) crystals with the c-axis normal to the substrate surface, whereas the L10-FePt and the L10-CoPt films include (100) crystals whose c-axis is parallel to the substrate surface in addition to (001) crystals. On MgO(110) substrates, the L10-FePt and the L10-FePd films involve (110) and (011) crystals whose c-axes are respectively in-plane and about 45° canted from the perpendicular direction, while the L10-CoPt film consists of a (110) crystal. (111)-oriented L10-FePt and L10-FePd films with the c-axis about 55° canted from the perpendicular direction epitaxially grow on MgO(111) substrates with six variants. Metastable L11 ordered phase formation is recognized for CoPt films epitaxially grown on MgO(111) substrates. As the substrate temperature increases up to 300 °C, the L11 ordering degree increases. With further increasing the substrate temperature, the ordering degree declines. No ordered phases are recognized for CoPd films. The magnetic properties are influenced by the crystal structure, the film orientation, and the ordering degree.
