“…This fact can be explained by the freezing of the domain walls that occurs at low temperatures, which shows that the nonlinear behavior is directly related to the extrinsic effect. 17 An expected behavior is verified in soft PZT for all field amplitudes [Figs. 1(a) and 1(b)].…”

This work presents a study of the domain wall dynamics in Pb(Zr 1Àx Ti x )O 3 (PZT)-based piezoceramics by means of the temperature dependence non-linear dielectric response and hysteresis loop measurements. In soft PZT, non-linear response gradually increases as the temperature is raised. A similar response is displayed by hard PZT at low temperatures. However, rather more complex behavior is detected at temperatures above 200 K. The anomalous response, which is very marked at room temperature, becomes even greater when the electric field is increased. The non-linear dielectric response is analyzed in the framework of the Rayleigh model. The results suggest a clear change in the domain wall dynamics in hard PZT, which is not observed in soft PZT. Observation of the hysteresis loops confirms that a strong effect of domain wall pinning emerges near room temperature. The change in domain wall dynamics appears as the main cause of the dielectric response difference between both kinds of materials at room temperature. V C 2012 American Institute of Physics.

“…In poled ferroelectric materials, this behavior can be associated with either an internal electric field developed during the poling process or result from an average polarization bias in the forward direction. Asymmetry may also be rationalized to occur from extrinsic effects, where the extent of domain wall motion in the positive and negative directions may differ [2,24,25]. Considering domain wall motion as the movement of domain walls across an energy landscape of pinning centers, such asymmetry in the degree of domain wall motion can be described using an asymmetric energy landscape about a mean domain wall position.…”

“…Domain wall motion is known to significantly affect the dielectric, piezoelectric, and magnetic properties of ferroic materials [1][2][3][4][5]. The motion of a domain wall through the lattice can be described by a force profile which represents the distribution and strength of various pinning centers [6].…”

Deaging and Asymmetric Energy Landscapes in Electrically Biased Ferroelectrics

In ferroic materials, the dielectric, piezoelectric, magnetic, and elastic coefficients are significantly affected by the motion of domain walls. This motion can be described as the propagation of a wall across various types and strengths of pinning centers that collectively constitute a force profile or energetic landscape. Biased domain structures and asymmetric energy landscapes can be created through application of high fields (such as during electrical poling), and the material behavior in such states is often highly asymmetric. In some cases, this behavior can be considered as the electric analogue to the Bauschinger effect. The present Letter uses time-resolved, high-energy x-ray Bragg scattering to probe this asymmetry and the associated deaging effect in the ferroelectric morphotropic phase boundary composition 0:36BiScO 3 À 0:64PbTiO 3 .

“…In general, the motion of non-180° domain walls under subcoercive fields is considered as the most important extrinsic contribution to the piezoelectric properties of ferroelectric ceramics and may reach up to 60-70% of the total piezoelectric response. [24][25][26] Thus, besides large switchable strain, BiFeO 3 ceramics are expected to exhibit relatively large weak-field piezoelectric response.…”

We report on the frequency and stress dependence of the direct piezoelectric d 33 coefficient in BiFeO 3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.e., dependence of d 33 on the amplitude of the dynamic stress. The nonlinear response suggests a large irreversible contribution of non-180° domain walls to the piezoelectric response of the ferrite, which, at present measurement conditions, reached a maximum of 38% of the total measured d 33 . In agreement with this interpretation, both types of non-180° domain walls, characteristic for the rhombohedral BiFeO 3 , i.e., 71° and 109°, were identified in the poled ceramics using transmission electron microscopy (TEM). In support to the link between nonlinearity and non-180° domain wall contribution, we found a correlation between nonlinearity and processes leading to deppining of domain walls from defects, such as quenching from above the Curie temperature and high-temperature sintering. In addition, the nonlinear piezoelectric response of BiFeO 3 showed a frequency dependence that is 2 qualitatively different from that measured in other nonlinear ferroelectric ceramics, such as "soft" (donor-doped) Pb(Zr,Ti)O 3 (PZT), i.e., in the case of the BiFeO 3 large nonlinearities were observed only at low field frequencies (<0.1 Hz); possible origins of this dispersion are discussed. Finally, we show that, once released from pinning centers, the domain walls can contribute extensively to the electromechanical response of BiFeO 3 ; in fact, the extrinsic domain-wall contribution is relatively as large as in Pb-based ferroelectric ceramics with morphotropic phase boundary (MPB) composition, such as PZT. This finding might be important in the search of new lead-free MPB compositions based on BiFeO 3 as it suggests that such compositions might also exhibit large extrinsic domain-wall contribution to the piezoelectric response. a) Electronic mail: tadej.rojac@ijs.si 3
