“…carried out a large number of dynamic mechanical and electrical performance studies on PZT-5H from 2014 to 2019, and obtained the mechanical response and piezoelectric characteristics of the piezoelectric ceramics under different strain rates, and evaluated the electrical output characteristics of the laminated piezoelectric ceramics under overload conditions, and the influence mechanism of the internal cracks on the discharge characteristics of the ceramics were studied. In 2020, Flannigan et al [18] . found that the energy index of PZT was strongly dependent on temperature, and evolved into a superposition value of about 2.0 with the change of temperature.Wang et al [19] .…”

In order to study the electromechanical characteristics of PZT-5H in the temperature range of -40~25℃ under the impact loading, the electrostatic parameters of PZT-5H at different temperatures are measured, the liquid nitrogen cooling/Hopkinson mechanical property and piezoelectric ceramic voltage output testing system are built, Hopkinson experiments at different temperatures (-40 ℃ , -25 ℃ , -10 ℃ , 0 ℃ and 25 ℃ ) and different impact velocities are carried out. Experimental results show that , the resistivity and relative permittivity decrease with the temperature of PZT-5H decreasing from 25℃ to -40℃, and the relative permittivity decrease about 27.92%, and the relaxation time is also deduced. By scanning electron microscope (SEM) and Energy Dispersive Spectrometer (EDS) observation, it is found that the blowhole defects and cracks of the piezoelectric ceramics have obvious effects on the electrical output characteristics of piezoelectric ceramics when the piezoelectric ceramics are struck. Based on the analysis of space charge theory, the freezing effect of piezoelectric ceramics caused by the obstruction of domain motion at low temperature is obtained. And the dynamic piezoelectric constant in the elastic region measured is about 1.66 times that of the static piezoelectric constant, which indicates that the relative dielectric constant of the piezoelectric ceramic has changed significantly under dynamic loading.

“…15,16 Later, it was shown that the Barkhausen noise represented an example of the self-organized criticality 17 and could be analyzed in terms of avalanche statistics in both ferromagnets [18][19][20] and ferroelectrics. [21][22][23][24] This universal approach makes it possible to characterize, by critical exponents, the behavior of a broad range of natural phenomena, such as earthquakes, 25 plastic deformations, 26,27 vortex in superconductors, 28 magnetic skyrmions, 29 stars dimming, 30 and even fluctuations in the financial markets. 31 The detailed analysis of the discrete events allows revealing the universality class underlying the particular physical system.…”

“…35 The analysis methods of the BPs in ferroelectrics can be divided into two groups: statistical methods and the analysis of the shape of the individual BP. The statistical methods based on the analysis of counting rate, duration, amplitude, and energy distribution functions of the BPs are more widespread due to their relative experimental simplicity (recording the switching current or acoustic emission 13 is required only) and universality 9,15,[21][22][23][36][37][38] (see Ref. 21 for the comprehensive review).…”

The analysis of the shapes of Barkhausen pulses (BPs) was used for the detailed characterization of the domain merging process in congruent lithium niobate LiNbO 3 (CLN) crystals. The BPs in ferroelectrics manifest themselves as the sharp peaks in a switching current during polarization reversal by the application of a constant or slow-varying external electric field. Three mechanisms of the BPs were previously proposed: domain nucleation, interaction of the domain walls with the pinning centers, and domain merging. We have revealed the domination of the domain merging mechanism for the generation of the BPs in CLN and classified the scenarios of domain structure evolution after merging in terms of the appearance and transformation of short-lived fast and superfast domain walls. We have shown that the input of merging events reaches 80% of the whole switching process. Two revealed types of BPs corresponding to the merging events considerably differ by duration and shape, thus opening the way for solution of the inverse problem-extracting the quantitative information about the domain kinetics by the analysis of the BPs. This analysis allows extracting the velocities of the fast and superfast walls and provides the possibility to go beyond the temporal resolution of the in situ imaging system in studying the superfast domain wall motion. The proposed analysis is applicable for the faceted growth of polygonal domains in any ferroelectric. It is necessary to point out that the analysis of the BPs allowed characterizing the main part of the domain evolution process in CLN as the fast domain transformations after merging prevail during the polarization reversal.

Acoustic emission study on avalanche dynamics of ferroelectric switching in lead zirconate titanate ceramics

The avalanche dynamics of ferroelectric switching in lead zirconate titanate ceramics was investigated using acoustic emission. Two distinct power-law regimes for ferroelectric switching events were identified by an anomaly in the histogram of probability density, in contrast to the single power-law behavior observed in BaTiO3 single crystals. Such an anomaly is ascribed to the different minimum cut-offs of two power-law distributions. The critical energy exponents were determined to be 1.25 ± 0.10 for energies <103 aJ and 1.51 ± 0.14 for energies >103 aJ. The events in both regimes can be attributed to the depinning of domain walls from two distinct types of defects. The events in the lower energy regime are associated with domain wall junctions due to long-range electric and elastic interactions, whereas the latter is related to extrinsic defects, such as vacancies and dislocations. Moreover, for both regions, the rate of aftershocks follows the Omori power-law, indicating the same critical temporal correlations between the avalanches.
