The structure of La 0.8 Sr 0.2 Ga 0.85 Mg 0.15 O 2.825 was studied by powder neutron diffraction and transmission electron microscopy. Neutron powder diffraction revealed cubic symmetry but electron diffraction and imaging showed the presence of local superstructures with symmetry lower than the ave
