A series of 5ve Ln 0.7 M 0.3 MnO 3 perovskites (Ln ‫؍‬ trivalent lanthanide; M ‫؍‬ divalent alkaline earth) has been prepared. These have the same mean A-cation site radius of 1.26 A s (equivalent to a perovskite tolerance factor of 0.98) but varying amounts of A-cation size disparity quanti5ed by t
