Fig. 4: Quantitative analysis of coupling between O-anions displacement and A/B-cations displacement.

a–d The horizontal component of atomic displacement and spontaneous polarization for each atomic row is plotted as a function of distance along the y-direction for PbZrO3 and PLZST system. The purple, green, orange, and red profiles represent the A-cations, B-cations, O-anions, and Ps, respectively. The value of these profiles are calculated from the Fig. 3a–d, where the displacement are defined as negative value when it aligns to the left. The corresponding profiles for vertical component are presented in Supplementary Fig. 8. The error bars represent the standard deviation measured from the experimental image.
