(a) Co-doping motifs in rutile. Numbers show different positions of the second atom in the co-doping pair with respect to the first (central) atom, shown in green; (b) BaPbSr2Ti4O12 structure derived by substitutions in the Pnma CaTiO3; (c) Ba2SeZrO6 cubic double perovskite with a rocksalt B-site cation ordering.
