Noncentrosymmetric Cation Order in the Cubic Perovskite Ba(4)CaFe(3)O9.5

The syntheses and characterization of the acentric, B-cation ordered phase Ba4CaFe3O9.5 and a topotactically oxidized product Ba4CaFe3O10.7 are reported. Utilizing electron diffraction and neutron powder diffraction data, cation ordered structures based on a cubic perovskite lattice were refined for...
