The layer group analysis combined with Landau theory was used to investigate the polar properties of antiphase boundaries (APBs) in SrTiO3 and PbZrO3. It was shown that in addition to the biquadratic coupling of the order parameter and polarization in the Landau-Ginzburg free energy expansion, additional rotopolar terms of antiphase boundaries contribute considerably to the polarization in these materials.
