Piezoelectricity in perovskite-type pseudo-cubic ferroelectrics by partial ordering of off-centered cations

Communications Materials, 2020
Strong piezoelectricity is typically due to reorientation of ferroelectric domains and is not expected in cubic systems. Here, the strong piezoelectricity of pseudo-cubic 0.3BaTiO3–0.1Bi(Mg1/2Ti1/2)O3–0.6BiFeO3 is explained in terms of partial ordering ...
