Summary: The origin of large electrostrain in BiFeO3-BaTiO3 ceramics is controversial, with some attributing it to a field-induced transition to a long-range ferroelectric state and others to the presence of multi-symmetry polar nanoregions. The BF-xST solid solution shows optimized electrostrain at x = 0.4, composed of rhombohedral cores surrounded by pseudocubic shells, indicating the existence of multi-symmetry polar nanoregions rather than a long FE phase.
