Structural analysis of epitaxial LSMO ultrathin films grown on STO.
(a) Typical RHEED intensity oscillations for the growth. The inset shows the RHEED patterns of STO prior to the growth (left) and LSMO film after the growth on STO (right). (b) The typical AFM image. (c) An AFM line profile across the terraces that is marked with a line in the Fig. 1(b). (d) XRD θ-2θ scan taken around the (002) peaks of STO and LSMO.
