(a) A simple model for PZN comprising polar domains oriented normal to each of the six {110} directions. Blue arrows indicate the direction of the displacements of Pb ions from their average position. (b) Single layer normal to [[1\bar{1}0]] in the resulting simulation array, showing the polar nanoregions (PNRs) that have formed. (c) The structure viewed down [[1\bar{1}0]] showing the direction of displacement of the different ions in a polar nanodomain (see Welberry, Gutmann et al., 2005BB102; Welberry et al., 2006BB100). (b) is based on Fig. 4[link](a) of Welberry et al. (2006BB100).
