Image of FIG. 1.
FIG. 1.

(a) Typical cross-section bright-field TEM micrograph of the epitaxial film grown on the (100) plane of single crystal substrate. (b) SAED patterns recorded from the area covering both the film and the substrate. The diffraction spots are indexed with magnetite.

Image of FIG. 2.
FIG. 2.

(a) Typical noise-filtered HRTEM image recorded at the interface area and (b) and the unfiltered image. The FFT patterns from (c) the substrate, (d) the local interface area, and (e) the films. (f) A reconstructed image using a pair of (222) reflections, showing misfit dislocations at the interface.

Image of FIG. 3.
FIG. 3.

(a) HRTEM image of the film containing two twin boundaries parallel to the {111} plane. (b) FFT pattern of (a), showing two sets of diffraction patterns with a 180° rotation symmetry. (c) HRTEM image of the film showing overlapped matrix∕twin area on the upper right side. (d) FFT pattern of (c), displaying additional spots that resulted from double diffraction such as the one at of {111} reflection.

Image of FIG. 4.
FIG. 4.

Noise-filtered HRTEM image of the film on the substrate. The dash line indicates the position of an APB in the film.

Image of FIG. 5.
FIG. 5.

Energy-filtered TEM image of the film recorded with (a) zero-loss electrons, (b) Fe edge electrons, and (c) Ti edge electrons. (b) and (c) show Fe and Ti maps, respectively, obtained by a standard three-window method.

FIG. 6.

Magnetic field dependence of MOKE ellipticity for the epitaxial layer on strontium titanate.
