Stairlike aurivillius phases in the pseudobinary Bi5Nb3O15-ABi2Nb2O9 (A = Ba and Sr) system: a comprehensive analysis using superspace group formalism
Original language description
We report the possibility of extending the so-called stairlike Aurivilius phases in the pseudobinary Bi5Nb3O15−ABi2Nb2O9 (A = Ba and Sr) over a wide range of compositions. These phases are characterized by a discontinuous stacking of [Bi2O2] slabs and perovskite blocks, leading to long-period intergrowths stabilized as a single phase. When analyses from precession electron diffraction tomography and Xray and neutron powder diffraction are combined, the monoclinic incommensurately modulated structure could be generalized to the Bi5Nb3O15−ABi2Nb2O9(A = Ba and Sr) compounds. This study highlights the compositional flexibility of stairlike Aurivillius phases.
