Abstract

This paper considers stacking fault disorder in Ba₃M₁Nb₂O₉ (M=Mn²⁺ or Co²⁺) 1:2 triple perovskites and how best to model it when refining neutron powder diffraction data. The true local structures of both samples were successfully refined using a coherent stacking fault disordered model. The stacking fault disorder in Ba₃MnNb₂O₉ and Ba₃CoNb₂O₉ affects their dielectric properties.
