N2 - Magnetic domain structure of FePt(011) films, which show huge magnetocrystalline anisotropy, was observed by electron holography and Lorentz microscopy. Although these methods have advantages for the microanalysis of magnetic domains, e.g., the high spatial resolution, detection of the magnetic signal is rather difficult, when the magnetization vector is parallel to the incident electron beam like the case of FePt(001) films. Here we demonstrate that the intensive observations are possible when the specimen is tilted in a microscope so that the magnetic flux perpendicular to the incident beam is generated. The holography experiment using the cross-sectioned specimen also provided useful information about the stray magnetic field of the FePt(011) films.
