The atomic polarization vector embedded in HAADF images viewed from [100]c at the (a) SMT-S and (b SMT-W regions (the types I and II in (a) represent T and R/O phases, respectively). Arrows of varying lengths and colors are used to represent the magnitude and direction of the polarization vectors, respectively (The polarization magnitude is uniformly amplified by 25 times). c, d Magnified images selected from (a) and (b). A, B, and C are the magnified mappings of selected regions in (c) and (d), respectively. e A schematic illustration of the polarization vector model in different directions. f Histograms of the magnitude and direction of the polarization vectors in different regions of SMT ceramics.
