Figure 5. The bright-field observations of the evolution of AFE domains during (A-C) heating and (D-F) cooling in PLZS. The yellow dashed lines and arrows in (A, C, and E) indicate the AFE domain wall. The green arrows depict dislocation arrays. AFE: Antiferroelectric; PLZS: (Pb0.97La0.02)(Zr0.50Sn0.50)O3.
