“…Therefore, the giant local strain and stress gradients caused by the volume variation between the AFE and FE unit cells may bring about higher value 𝛽 and the frequency dependence of domains orientation. 45,51,59 Figure 6C,D illustrates the frequency dependence of the electric hysteresis (Δ𝐸) of PLZST and PLBZST. As the measurement frequency increased from 0.1 to 1000 Hz, the electric hysteresis (Δ𝐸 =𝐸 AFE−FE − 𝐸 FE−AFE ) of PLZST increased monotonically from 1.23 to 2.29 kV/mm, and the empirical formula Δ𝐸 = 1.06 + 0.2681×𝑓 0.219 fitted well with the measurement result (𝑅 2 > 0.99).…”

Antiferroelectric (AFE) ceramics are promising for applications in high-power density capacitors, transducers, etc. The forward switching field (𝐸 AFE−FE ) and backward switching field (𝐸 FE−AFE ) are critical performance indicators for AFE ceramics, and the coupling between the structure transition and domain orientation makes them different from the coercive field (𝐸 C ) of ferroelectric (FE). Moreover, in practical applications, AFE ceramics are often required to operate at varying frequencies. However, systematic studies regarding the frequency dependence of 𝐸 AFE−FE and 𝐸 FE−AFE are insufficient. In this work, Pb 0.98 La 0.02 [(Zr 0.55 Sn 0.45 ) 0.88 Ti 0.12 ] 0.995 O 3 (PLZST) AFE ceramic was fabricated, and two empirical formulas (𝐸 AFE−FE = 𝐴+𝐾 𝐴 × 𝑓 𝛽 , 𝐸 FE−AFE = 𝐹−𝐾 𝐹 × 𝑓 𝛽 ) were proposed to predict the frequency dependence of 𝐸 AFE−FE and 𝐸 FE−AFE .The formulas are based on the electric field-induced phase transition characteristics of AFE and the Kolmogorov-Avrami-Ishibashi domain nucleationswitching model. Furthermore, the dynamic hysteresis loops of PLZST at various frequencies (1-1000 Hz) and temperatures (30-230 • C) were investigated. The results show that the electric field-induced phase transition of AFE ceramic is dominated by the coupling between the structural transition and domain orientation. The domain orientation hinders the structure transition, leading to an increase in 𝐸 AFE−FE and a decrease in 𝐸 FE−AFE as the frequency of applied electric field increases. Meanwhile, the domain growth process is affected by the structure of AFE, and the value of 𝛽 (domain growth dimensionality) increases with the stability of the AFE structure. For comparison, Pb 0.86 La 0.02 Ba 0.12 [(Zr 0.55 Sn 0.45 ) 0.88 Ti 0.12 ] 0.995 O 3 (PLBZST) relaxor FE ceramic was fabricated. Due to the high mobility of the microdomain, the dynamic hysteresis loop of PLBZST ceramic exhibits excellent frequency stability. The charge-discharge experiment with an ultrahigh equivalent frequency (𝑓 equivalent >100 kHz) was performed to investigate the frequency stability of energy release of PLZST and PLBZST. The results may provide guidance for research pertaining to ceramic capacitors with high-power density and highfrequency stability.

The figure-of-merits of ferroelectrics for transducer applications are their electromechanical coupling factor and the operable temperature range. Relaxor-PbTiO3 ferroelectric crystals show a much improved electromechanical coupling factor k33 (88~93%) compared to their ceramic counterparts (65~78%) by taking advantage of the strong anisotropy of crystals. However, only a few relaxor-PbTiO3 systems, for example Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3, can be grown into single crystals, whose operable temperature range is limited by their rhombohedral-tetragonal phase transition temperatures (Trt: 60~120 °C). Here, we develop a templated grain-growth approach to fabricate <001>-textured Pb(In1/2Nb1/2)O3-Pb(Sc1/2Nb1/2)O3-PbTiO3 (PIN-PSN-PT) ceramics that contain a large amount of the refractory component Sc2O3, which has the ability to increase the Trt of the system. The high k33 of 85~89% and the greatly increased Trt of 160~200 °C are simultaneously achieved in the textured PIN-PSN-PT ceramics. The above merits will make textured PIN-PSN-PT ceramics an alternative to single crystals, benefiting the development of numerous advanced piezoelectric devices.
