Abstract

A large electrostrain of 14;0.245% emerged in an intrinsic-acceptor-doped morphotropic phase boundary (MPB) system Ba(Ce _0.1 Ti _0.9 )O ₃ -x(Ba _0.7 Ca _0.3 )TiO ₃ under an electric field of 30 kV/cm at 0.1 Hz. It is almost twice as that of hard lead zirconate titanates and larger than the strains of other barium-titanate-based systems with either the aging effect or MPB effect. This large electrostrain is induced by the coupling of the aging effect and MPB effect in the MPB composition. More interestingly, it is found that, different from the aged single-phase samples, the aged MPB sample shows a more obvious increase in electrostrain but a slighter decrease in saturation polarization. The explanation for this abnormal aging effect around MPB has been proposed on the basis of the symmetry-conforming principle of point defects. This work demonstrates that the ferroelectric aging effect around MPB could be an effective tool to achieve a large electrostrain in ferroelectrics.
