“…As a result, E C increases and E i appears. Albeit some experimental investigations support the idea that the P D is stable during ferroelectric phase transition, the observation in our experiment may provide additional information to that belief. Hypothesizing P D does not change after T RT , the E i would decrease substantially because the defect dipoles with P D lined along <111> have smaller pinning effect on polarization reversal along <001> in T phase.…”

Orientation dependence of electrical properties and domain configurations of 8 mol% Mn-doped rhombohedral PIN-PT (0.68Pb(In 0.5 Nb 0.5 )O 3 -0.32Pb (Ti 0.92 Mn 0.08 )O 3 ) rhombohedral single crystals were investigated with an emphasis on studying the variations of coercive field (E C ), internal field (E i ) on domain patterns. Our results showed that for both [001] and [110]-oriented samples, the

“…During the cooling through the T C , domain realignment does occur slowly in small steps as time elapses. The mechanism of this aging process is mainly attributed to the presence of mobile charge species, such as defect or defect dipoles, which usually stabilize the domain pattern and decrease the domain wall contribution to the polarization response . This phenomenon is more obvious in accepted‐doped ferroelectric materials, such as Fe 3+ ‐doped PZT ceramics, where the oxygen vacancies are present to keep the electronic equilibrium due to the lower valence replacement of the Fe 3+ ions for (Zr 4+ ,Ti 4+ ) ions, forming the defect dipoles

Due to the nature of domains, ferroics, including ferromagnetic, ferroelectric, and ferroelastic materials, exhibit hysteresis phenomena with respect to external driving fields (magnetic field, electric field, or stress). In principle, every ferroic material has its own hysteresis loop, like a fingerprint, which contains information related to its properties and structures. For ferroelectrics, many characteristic parameters, such as coercive field, spontaneous, and remnant polarizations can be directly extracted from the hysteresis loops. Furthermore, many impact factors, including the effect of materials (grain size and grain boundary, phase and phase boundary, doping, anisotropy, thickness), aging (with and without poling), and measurement conditions (applied field amplitude, fatigue, frequency, temperature, stress), can affect the hysteretic behaviors of the ferroelectrics. In this feature article, we will first give the background of the ferroic materials and multiferroics, with an emphasis on ferroelectrics. Then it is followed by an introduction of the characterizing techniques for the loops, including the polarization–electric field loops and strain–electric field curves. A caution is made to avoid misinterpretation of the loops due to the existence of conductivity. Based on their morphologic features, the hysteresis loops are categorized to four groups and the corresponding material usages are introduced. The impact factors on the hysteresis loops are discussed based on recent developments in ferroelectric and related materials. It is suggested that decoding the fingerprint of loops in ferroelectrics is feasible and the comprehension of the material properties and structures through the hysteresis loops is established.

“…Aging effect can significantly modify the electric performance of the materials and plays an important role in practical applications, as in the case of aging‐induced large electrostrain, which may lead to novel applications in ultralarge stroke and nonlinear actuators . e.g., BaTiO 3 single crystal shows a huge recoverable electrostrain of 0.75% (at 2.0 kV/cm) after the aging process.…”

In this work, we studied aging and fatigue behaviors of 1.0 mol %Cu-modified (Na 0.5 K 0.5 )NbO 3 lead-free ceramics with doubleloop-like characteristic, and found an interesting result of electric field cycling induced large electrostrain in the aged samples. After the "aging" treatment, the hysteresis loop "closes" totally and constricts completely at zero electric field, accompanying with a large nonlinear electrostrain of about 0.26%. More interestingly, the electrostrain in the aged sample is sensitive to the field cycling, which is pushed to a higher level of 0.47% approaching that of some Pb-based antiferroelectric materials. A microscopic model of the domain switching-related electrostrain effect is proposed to explain the field cycling induced large electrostrain in the aged samples. It can be identified due to the weakening of intrinsic restoring force for reversing the switched domains, induced by the point defects (defect dipoles) migration aligning along field direction during cycling, evident by the gradually "opened" hysteresis loop with cycling.S.
