Permissible symmetries of multi-domain structures are analyzed in the m3m→3m, m3m→4mm and m3m→mm2 ferroelectric species. Domain structures produced by the application of external electric and/or mechanical fields that allow for the formation of two-dimensional domain superlattice are described in terms of effective group symmetry. Based on our analysis, the most perspective directions for properties enhancement through domain engineering are specified for perovskite ferroelectric crystals having tetragonal, rhombohedral, and orthorhombic symmetries. © 2003 American Institute of Physics.
