“…Sundar and Newnham presented detailed expressions for the coefficients f and g according to the Born-Mayer potential with which the electrostrictive coefficient Q was accurately calculated for a LiF crystal giving the value of 0.53 m 4 /C 2 , which is consistent with the experimental result. 57 The effects of the microscopic characteristics on the electrostrictive coefficient Q were further demonstrated with the degree order of the B-site cations in perovskite materials. Table III shows that the magnitude of the electrostrictive coefficient strongly depends on the level of orderdisorder in the B-site cation arrangement.…”

Electrostriction plays an important role in the electromechanical behavior of ferroelectrics and describes a phenomenon in dielectrics where the strain varies proportional to the square of the electric field/ polarization. Perovskite ferroelectrics demonstrating high piezoelectric performance, including BaTiO3, Pb(Zr1-xTix)O3, and relaxor-PbTiO3 materials, have been widely used in various electromechanical devices. To improve the piezoelectric activity of these materials, efforts have been focused on the ferroelectric phase transition regions, including shift the composition to the morphotropic phase boundary or shift polymorphic phase transition to room temperature. However, there is not much room left to further enhance the piezoelectric response in perovskite solid solutions using this approach. With the purpose of exploring alternative approaches, the electrostrictive effect is systematically surveyed in this paper. Initially, the techniques for measuring the electrostrictive effect are given and compared. Second, the origin of electrostriction is discussed. Then, the relationship between the electrostriction and the microstructure and macroscopic properties is surveyed. The electrostrictive properties of ferroelectric materials are investigated with respect to temperature, composition, phase, and orientation. The relationship between electrostriction and piezoelectric activity is discussed in detail for perovskite ferroelectrics to achieve new possibilities for piezoelectric enhancement. Finally, future perspectives for electrostriction studies are proposed. 2014 AIP Publishing LLC.

“…The strength of the electrostriction effect is characterized by the electrostriction coefficient M e : where Y is the Young's modulus 22. Values of M e range from ∼10 −24 m 2 /V 2 in materials with low dielectric constants ( ϵ <50), to 10 −16 m 2 ·V −2 for materials with high dielectric constant ( ϵ >1000) used in mechanical actuators.…”

Gd-doped CeO(2) exhibits an anomalously large electrostriction effect generating stress that can reach 500 MPa. In situ XANES measurements indicate that the stress develops in response to the rearrangement of cerium-oxygen vacancy pairs. This mechanism is fundamentally different from that of materials currently in use and suggests that Gd-doped ceria is a representative of a new family of high-performance electromechanical materials.

“…Secondly, the possible reason may result from the electrostrictive effect of PZT films during reannealing treatment in AEF. Dielectrics will take on electrostrictive effect in the applied electric field [11], so the electrostrictive effect of PZT in AEF would lead to the alternating volume change of PZT film during reannealing treatment in AEF, and then gives another activation force of the local plastic deformation in the Pt layer.…”
