Stacking fault disorder and its diffraction consequences in Ba 3 MNb 2 O 9 (M = Co and Mn) 1:2 triple perovskites

Liu, Yun; Withers, Raymond; Ting, Valeska; Fitz Gerald, John; Noren, Lasse


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.
