摘要: The room temperature structures of the four-layer Aurivillius phase ferroelectrics CaBi4Ti4O15 and BaBi4Ti4O15 are determined by means single crystal X-ray diffraction. Regarding phase, in agreement with tolerance factor, a significant deformation perovskite blocks is observed. rotation system octahedra typical from even layer phases leads to use space group A21am. For only weak variation respect F2mm can be suggested A presence Ba atoms [M2O2] slabs confirmed previous works but specific Ba2+ Bi3+ sites have considered due large difference bounding requirement these cations. Possible origins for ferroelectric relaxor behavior Ba-based compound discussed view presented structural analyses.
