“…Similar anisotropic behavior was also reported in other ionic crystals possessing oxygen octahedral structures (LiNbO 3 , LiTaO 3 , KNbO 3 , and Ba 2 NaNb 5 O 15 crystals), as listed in Table V. 54 As demonstrated in Ref. 53, the anisotropy of the electrostriction in perovskite crystals led us to believe that it is inherently associated with the oxygen octahedra.…”

“…The longitudinal coefficients Q 33 and Q 11 for soft elastomers are on the order of 10 4 m 4 /C 2 , while those for perovskite ferroelectrics are about 10 À1 to 10 À2 m 4 /C 2 , as listed in Table II. 11,37,[51][52][53][54][55][56] The electrostrictive Q coefficients have been analyzed with respect to the microstructures and macroscopic properties of the materials.…”

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.

“…[18] (e.g., an electric field of magnitude 1.2 GV m −1 will induce a volume expansion of 0.2%). The extracted fit value obtained for M 11 of 1970 pm 2 V − 2 agrees very well with the experimental values of 2020 pm 2 V −2 [ 36 ] (a difference of 2%). We have also calculated the coefficients q 11 , q 12 , m 11 , and m 12 , by fixing the lattice constants, relaxing the internal coordinates under applied E and D fields, and fitting the subsequent stress dependence on P or E field, respectively.…”

In this work a new method for the calculation of the electrostrictive properties of materials using density functional theory is presented. The method relies on the thermodynamical equivalence, in a dielectric, of the quadratic mechanical responses (stress or strain) to applied electric stimulus (electric or polarization fields) to the strain or stress dependence of its dielectric susceptibility or stiffness tensors. Comparing with current finite‐field methodologies for the calculation of electrostriction, it is demonstrated that this presented methodology offers significant advantages of efficiency, robustness, and ease of use. These advantages render tractable the high throughput theoretical investigation into the largely unknown electrostrictive properties of materials, and the microscopic origins of giant electrostriction.

“…For Ce 0.8 Gd 0.2 O 1.9 , $ M_{_e}^{CGO} = 6.47 \pm 0.43 \times 10^{- 18} $ m 2 ·V −2 (Supporting Information, section 3), which is unusually high for a material with dielectric constant of $ \varepsilon _{_r}^{CGO} \approx 30 $ 10, 11. For example, for MgO (ϵ MgO ≈ 10) $ M_{_e}^{MgO} = 2 \cdot 10^{- 21} $ m 2 ·V −2 and for the relaxor ferroelectric 3% Ca‐doped PMN (PbMn 1/3 Nb 2/3 O 3 ) (ϵ CaPMN ≈ 4000) $ M_{_e}^{CaPMN} = 3.5 \cdot 10^{- 18} $ m 2 ·V −2 23. The difference between known electrostrictors and Ce 0.8 Gd 0.2 O 1.9 is also obvious in the maximum stress they can generate.…”

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.
