“…Switchable polarizations under an electric field allow ferroelectrics to be used in memory and logic devices 10 . In antiferroelectric compounds, two opposite polarizations arrange into two crystalline sub lattices, and the polarization vs. the electric field possesses the feature of a double P-E hysteresis loop, corresponding to the field-induced transition between the antiferroelectric and ferroelectric states 11 . Recently, this specific double P-E hysteresis loop has received attention due to its advantage for energy storage applications [11][12][13][14] .…”

Antiferroelectrics are of interest due to their high potential for energy storage. Here, we report the discovery of pinched, polarization-vs.-electric field (P-E) hysteresis loops in the lead-free tungsten bronze ferroelectrics Ba 4 Sm 2 Ti 4 Nb 6 O 30 and Ba 4 Eu 2 Ti 4 Nb 6 O 30 , while a broad, single P-E hysteresis loop was observed in the analogue compound Ba 4 Nd 2 Ti 4 Nb 6 O 30 . Pinched P-E loops are similar to antiferroelectric hysteresis loops, but in perovskites, they are mostly caused by an extrinsic, internal bias field due to defects, which block domain wall motion. We show that the pinched P-E loops are caused by an intrinsic effect, i.e., by the electric-field-induced phase transition from a nonpolar incommensurate to a polar commensurately modulated crystal structure. The in situ electron diffraction results show the coexistence of commensurate polar structural modulation and incommensurate non-polar modulation during the ferroelectric transition and within the ferroelectric phase below the transition temperature. This phase coexistence is the reason for the small remanent polarization. An external electric field transforms the incommensurate component into a commensurate one, and the polarization increases. This new mechanism for pinched P-E hysteresis loops in ferroelectrics not only indicates a new direction for the development of Pb-free ferroelectric materials for energy storage but also significantly contributes to the physical understanding of ferroelectricity in materials with a tungsten bronze structure.

“…Both the phenomenon itself and its underlying mechanisms are currently under intense investigation and review [2][3][4][5][6][7] . Kittel 8 initially assigned the term "antiferroelectric" to the crystal that has a structural phase transition from a highersymmetry nonpolar parent phase to a lower-symmetry nonpolar phase, distinguished from the parent phase by the anti-parallel ionic shifts.…”

We report the results of comprehensive study of the critical dynamics of the prototype perovskite antiferroelectric PbZrO3. The combination of inelastic X-ray and diffuse X-ray scattering techniques and Brillouin light scattering was used. It is found that the dispersion of the TA phonons is strongly anisotropic. The dispersion curve of the in-plane polarized TA phonons propagating in [1 1 0] direction demonstrates pronounced softening. Slowing down of the excitations at R-point is found, it is manifested in growing of the central peak. This slowing down is too weak to be considered as a primary origin of the corresponding order parameter. Obtained results are treated in terms of TA-TO flexoelectric mode coupling. It is demonstrated that the structural phase transformation in PbZrO3 can be considered as the result of the only intrinsic instability associated with the ferroelectric soft mode.

“…3(c) illustrates the capacitance C of PLZST10 versus E. At low field the value of C only increase slightly, but when E approaches 8kV/mm, the value of C grows rapidly due to the AFE-FE phase transition. 16,17 According to the expression of I max and equation (6), the increase of both E and C will result in a rise of increase rate of I max . Above 8 kV/mm, the field-induced FE phase becomes stable.…”

The pulse discharge properties of lead lanthanum zirconate stannate titanate (PLZST) antiferroelectric (AFE) ceramics, ferroelectric (FE) dielectrics, and linear dielectrics were compared in this paper. It is found that as the voltage increases, those three types of dielectrics display three different voltage-dependent regularities: the peak current (Imax) of linear dielectrics increases linearly with increasing voltage; the Imax of FE dielectrics rises up with a gradually declined increase rate; the Imax of PLZST AFE ceramics presents a three-stage growth and during the third stage, the regularity is similar with that of FE dielectrics. Furthermore, three advantages of PLZST AFE ceramics for pulse discharge can be determined: a large increase rate of Imax due the field-forced AFE-FE phase transition, a great enhanced power density and a relatively short discharge period time. These results would pave the way for understanding and utilizing AFE ceramics in pulse power application.
