Domain boundary (DB) structures are of great importance for understanding the structure-property relationship in many ferroic crystals. Here, we present atomically resolved DB configurations in PbZrO3-based antiferroelectric ceramics. The Pb-cation d

The existence of a variety of phases and their transitions in the electric field-temperature (E-T) space of relaxor ferroelectrics make them an interesting research subject. To directly observe the evolution of domain morphology and crystal symmetry
