Abstract Noncentrosymmetric (NCS) mixed metal oxide materials have been studied for decades because of their interesting physical properties, including ferroelectricity, piezoelectricity, pyroelectricity, multiferroicity, magnetoelectricity, and second harmonic generation (SHG). Several strategies along with first principles calculations have been proposed and investigated to search for new NCS oxide materials, however, it is still a challenge to design and to synthesize new NCS oxide materials with optimal characteristics. In this presentation, we will demonstrate that by ordering, or rearrangement of the B/B' cations the inversion symmetry of the parent centrosymmetric oxides (PbSb2O6-related and CaTa2O6-related, ABB'O6) could be broken. This strategy will help to design and synthesize new multifunctional NCS oxide materials.
