In this work, a reversible, large electric field induced strain of over 0.9% at room temperature, and in particular over 0.6% above 380 K was obtained. The polarization rotation path and the phase transition sequence of different compositions in these ternary systems have been determined with increasing electric field applied along [001] direction based on x-ray diffraction data. Thereafter, composition dependence of field-temperature phase diagrams were constructed, which provide compositional and thermal prospectus for the electromechanical properties. It was found the structural origin of the large stain, especially at higher temperature is the lattice parameters modulated by dual independent variables in composition of these ternary solid solution crystals.9application/pdfen-USCreative Commons Attribution 4.0 Internationalsingle-crystalselectric-fieldphase-transitionelectromechanical responsepolarization rotationneutron-diffractionbehaviortransformationsequenceoriginArticle - Refereedhttps://doi.org/10.1038/srep35120627734908
