| Abstract(in English) | The tilt angle of the crystal orientation axis was quantitatively evaluated for tilt-oriented magnetic film, and a method for separating the effective crystal magnetic anisotropy energy Kueff of the film from the intrinsic crystal magnetic anisotropy energy Kugrain of magnetic crystal particles was investigated. As a measurement sample, a Co/Pt multilayer magnetic film was formed on an underlayer composed of Ta and Pt by sputtering with a cylindrical collimator at an inclined incident angle of 60 deg. To quantitatively evaluate the crystal inclination angle, a rocking curve was measured with a three-dimensional polar-coordinate X-ray diffraction system, and in addition, the angle dependence of the magnetic switching field Hsw was measured with a Polar-Kerr system. It was also shown that both Kueff and Kugrain can be separated quantitatively even in tilt-oriented magnetic films by correcting the inclination angle of the crystal orientation axis when deriving the crystal magnetic anisotropy energy from a torque curve. |
