(a) Superimposed EELS maps of oxygen (red), Mn (green) and Co (blue) of La₂CoMnO₆ on LSAT from the same area as Figure 4b showing a clear zig-zag pattern of the oxygen positions, meaning strong correlated octahedral tilting; (b) ABF image (5 nm²) of La₂CoMnO₆ on SrTiO₃ at the interface showing a clear zig-zag of the oxygen positions, which is consistent with octahedral tilting; (c) plot of tilt angle for the octahedral tilting going from the SrTiO₃ substrate into La₂CoMnO₆, the dotted line is a guide-to-the-eye; (d) plot of (111)_pc spacings between A-site layers going from the LSAT substrate into the La₂CoMnO₆ film, the dotted line is a guide-to-the-eye; and (e) plot of (111)_pc spacings between A-site layers going from the SrTiO₃ substrate into the La₂CoMnO₆ film, the dotted line is a guide-to-the-eye.
