Stress- and temperature-dependent scaling behavior of dynamic hysteresis in soft PZT bulk ceramics

Electrocaloric Behavior and Temperature‐Dependent Scaling of Dynamic Hysteresis of Ba0.85Ca0.15Ti0.9Zr0.1O3 Ceramics

“…In Table , scaling constants β, γ, and η exhibit a relation of E c ∝ T β , P r ∝ T γ , and < A > ∝ T η , respectively. It can be seen that temperature scaling for soft PbZr 1−x Ti x O 3 is found to be < A > ∝ T −1.1 , which corresponds to the value obtained in this study . However, E C and P r based temperature‐dependent dynamic hysteresis scaling parameter differs as compared to other ferroelectric ceramics as listed in Table .…”

“…A number of studied have been published on the scaling behavior of dynamic hysteresis in ferroelectric materials . These are mainly focused on the hysteresis area as a function of applied electric/stress field(s), temperature, and frequency.…”

“…These are mainly focused on the hysteresis area as a function of applied electric/stress field(s), temperature, and frequency. This is due to the fact that electric field and frequency are important parameters for a number of applications such as sensor, actuators, transducers, pulse power, and medical applications . However, the performance of the ferroelectric material can further alter upon exposure to different working temperatures, as discussed by a number of researchers .…”

Temperature-Dependent Phase Transition in Orthorhombic [011]c Pb(Mg1/3Nb2/3) O3-0.35PbTiO3 Single Crystal

“…As shown in Figure 3b, P r decreases with temperature increasing, due to the so-called pyroelectric effect [24]. Owing to the decrease of interface energy of the ferroelectric domains with temperature increasing, the domain walls movement becomes easier, leading to the decline of E c [25]. The variation of temperature-dependent hysteresis loops indicates the movement of domain walls, crystal structure, as well as internal spontaneous polarization re-orientation.…”

Dielectric Properties of Pb(Zr1/2Ti1/2)O3-Pb(Zn1/3Nb2/3)O3Ceramics Under Compressive Stress Applied Perpendicular to Electric Field

“…Therefore, it is very important to obtain experimental data, as well as to better understanding how these materials behave under stress. The compressive stress dependence of dielectric properties has been investigated extensively in materials such as BaTiO 3 [13][14][15][16][17][18][19][20][21]. The results clearly showed that the effects of stress on the dielectric properties depended significantly on ceramic compositions and stress levels.…”
