Determination of B-site ordering and structural transformations in the mixed transition metal perovskites La2CoMnO6and La2NiMnO6

The low-and high-temperature structures of La2CoMnO6 and La2NiMnO6 have been refined using powder neutron diffraction. At low temperatures the materials adopt a charge-ordered monoclinic structure which transforms to a rhombohedral structure at elevated temperature without loss of charge ordering. T... View More
