A combined diffraction and dielectric properties investigation of Ba3MnNb2O9 complex perovskites
A combined synthesis, diffraction and dielectric properties investigation of the dependence (and effect) of Mn2+/Nb5+ ordering in Ba3MnNb2O9 (BMN) upon annealing atmosphere and processing conditions has been carried out. Annealing in different atmospheres was not found to significantly alter either nominal stoichiometry or structure type. The obtained structure type (disordered metrically cubic or ordered trigonal) as well as the measured electrical properties (in particular, the dielectric...[Show more]
