Abstract
- Flexoelectricity couples strain gradient to polarization and usually exhibits a large coefficient in the paraelectric phase of the ferroelectric perovskites. In this study, we employed the relaxor 0.3Pb(In<subscript>1/2</subscript>Nb<subscript>1/2</subscript>)O<subscript>3</subscript>-0.35Pb(Mg<subscript>1/3</subscript>Nb<subscript>2/3</subscript>)O<subscript>3</subscript>-0.35PbTiO<subscript>3</subscript> (PIN-PMN-PT) single crystals to study the relationship between flexoelectric coefficients and the crystal structure. The flexoelectric coefficients in PIN-PMN-PT single crystal are found to vary from 57 μC/m at orthorhombic/monoclinic phase to 135 μC/m at tetragonal phase, and decreases to less than 27 μC/m in the temperature above T<subscript>m</subscript>. This result discloses that ferroelectricity can significantly enhance the flexoelectricity in this kind of perovskite. [ABSTRACT FROM AUTHOR]
