(a) Exaggerated schematic view of a pseudo-merohedral twin pair owing to 180° rotation around [101] for orthorhombically distorted perovskite. (b) Calculated diffraction spots illustrating the splitting of the Bragg peaks. (c) Two-dimensional model of the two domains, each containing 9 × 9 unit cells, with the difference between the a and c dimensions being ten times greater than is the case for the PCMO crystals in order to magnify the effects for demonstration purposes. (d) Calculated scattering pattern using the nearBragg program from the two-dimensional twinned crystal given in (c).
