FIG. 1.

Low magnification HAADF image showing the morphology of thin films grown on (STO) substrate.

FIG. 2.

Composition spectrum along the route marked with a black line in Fig. 1. A vertical dotted line shows the location of the interface. The plots at the left side of this dotted line result from scanning of substrate. The plot, marked with a dotted square, results from the dark-band in the film.

FIG. 3.

(a) La-mapping image, (b) Mn-mapping image, and (c) O-mapping image. A combination of La and Mn map concludes that the bands, as seen in Fig. 1, are Mn-rich and La-poor, while oxygen seems homogeneous in the film.

Image of FIG. 4.
FIG. 4.

Low magnification plan-view HAADF image showing the distribution of the Mn-rich and La-poor nano-agglomerates. It is seen that they are highly dense and dimensionally uniform in the film. Note that each agglomerate has a much darker nuclei. An enlarged nano-agglomerate is shown as an inset.

Image of FIG. 5.
FIG. 5.

A plot showing compositions along the white line in the inset of Fig. 4. The dotted square correspond to the nano-agglomerate. It is seen that the composition within single agglomerate is fluctuated. The ratio of gets to maxim at the center of the agglomerate.
