Abstract

The electric‐field‐induced strain in single‐crystal BaTiO3 was investigated. For crystals relatively free of twinning, a longitudinal strain of 0.35% can be induced just above the ferroelectric‐paraelectric phase transition temperature (Tc1) primarily by field‐forced paraelectric‐ferroelectric phase transition. For heavily twinned crystals, 90° domain reorientation under the applied electric field plays an important role in the induced strain below Tc1, and an induced strain of 0.6% is observed a few degrees below Tc1. Above Tc1, the electrostrictive property measured by a weak excitation field is purely intrinsic. When the excitation field is large, so that a field‐forced paraelectric‐ferroelectric phase transition is involved, the x33/P23 value (where x33 and P3 are the induced strain and polarization along the z axis, respectively) is intrinsic at higher temperature, but may be modified at temperatures just at and slightly above Tc1 by residual 90° twin structure.
