(a) Low-magnification cross-sectional HREM image for film. The white arrow indicates the interface between film and substrate (LAO). Inset (A) is the XRD scan for the same film. The small inset in inset (A) presents the Bragg peak splitting, provided by the film (F) and the substrate (S) reflections. Inset (B) is the  zone-axis ED pattern prepared at RT. The presence of superlattice spots with a modulation wave vector similar to 1/2, 0, and 0 is evident. (b) High-magnification cross-sectional HREM image for a film area where different phases coexist. The dashed lines indicate the interphase boundaries.
(a) and (b) are the high-magnification cross-sectional HREM image and the corresponding FFT pattern for the unmodulated phase, respectively. Only the fundamental Bragg peaks are indicated. [(c) and (d)] The same pictures for the modulated phase with the doubled -axis lattice period parallel to the -axis direction. The presence of superlattice spots with a modulation wave vector, similar to 1/2, 0, and 0, is evident. [(e) and (f)] The same pictures for the strip-domain phase formed inside the film. The short white arrows indicate the period of strip domains in the (e) real and the (f) reciprocal space.
Temperature dependence of the in-plane FC (solid symbols) and ZFC (open symbols) magnetic moment and the reduced magnetic moment (open symbols for the right scale) for film in an applied magnetic field of 100 Oe. The vertical arrows indicate the temperatures of FM , AFM , and Griffiths/PM transitions. The inset displays the in-plane hysteresis loop taken at 5 K. The lines are guides to the eyes.
