Abstract

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{sub 3}-0.64PbTiO{sub 3}.

Extensive domain wall motion and deaging resistance in morphotropic 0.55Bi(Ni{sub 1/2}Ti{sub 1/2})O{sub 3}–0.45PbTiO{sub 3} polycrystalline ferroelectrics

Journal Article Tutuncu, Goknur; Fan, Longlong; Chen, Jun; ... - Applied Physics Letters

Domain wall motion is known as a major source of extrinsic contributions to the dielectric and piezoelectric properties of ferroelectric materials. In the present work, we report the extent of non-180° domain wall motion during strong and weak electric field amplitudes in situ using time-resolved, high-energy X-ray diffraction in the ferroelectric morphotropic phase boundary composition 0.55Bi(Ni{sub 1/2}Ti{sub 1/2})O{sub 3}–0.45PbTiO{sub 3} (BNT-45PT). After application of strong electric fields, two phases are shown to coexist. In the tetragonal phase of this material, the extent of 90° domain wall motion is significant and the domain alignment is nearly saturated. Weak (subswitching) cyclic electricmore »« less

Extrinsic contributions to the response in ferroelectric ceramics

Miscellaneous Li, S

The interest of this thesis is to investigate the electromechanical properties of ferroelectric ceramics in terms of the motion of domain walls, movement of boundaries between interphases, and interactions between grains and domains. A tentative phenomenological model has been proposed to evaluate the piezoelectric, elastic and dielectric parameters attributed to non-180[degrees] domain wall motions in ferroelectric ceramics. Observations of dielectricity and piezoelectricity at low and high temperatures, at small and large external fields, and at medium and high frequencies are discussed. From observed linear and nonlinear behavior of PZT ceramic systems, it can be concluded that the nonlinear effects aremore »« less
Precipitation Hardening in Ferroelectric Ceramics

Journal Article Zhao, Changhao; Gao, Shuang; Yang, Tiannan; ... - Advanced Materials

Domain wall motion in ferroics, similar to dislocation motion in metals, can be tuned by well-concepted microstructural elements. In demanding high-power applications of piezoelectric materials, the domain wall motion is considered as a lossy hysteretic mechanism that should be restricted. Current applications for so-called hard piezoelectrics are abundant and hinge on the use of an acceptor-doping scheme. However, this mechanism features severe limitations due to enhanced mobility of oxygen vacancies at moderate temperatures. By analogy with metal technology, the authors present here a new solution for electroceramics, where precipitates are utilized to pin domain walls and improve piezoelectric properties.

Correlation between piezoresponse nonlinearity and hysteresis in ferroelectric crystals at nanoscale

Journal Article Kalinin, Sergei; Jesse, Stephen; Yang, Yaodong; ... - Applied Physics Letters

Here, the nonlinear response of a ferroic to external fields has been studied for decades, garnering interest for both understanding fundamental physics, as well as technological applications such as memory devices. Yet, the behavior of ferroelectrics at mesoscopic regimes remains poorly understood, and the scale limits of theories developed for macroscopic regimes are not well tested experimentally. Here, we test the link between piezo-nonlinearity and local piezoelectric strain hysteresis, via AC-field dependent measurements in conjunction with first order reversal curve (FORC) measurements on (K,Na)NbO₃ crystals with band-excitation piezoelectric force microscopy. The correlation coefficient between nonlinearity amplitude and the FORC ofmore »« less
