Antiferroelectric (AFE) materials are of great interest owing to their scientific richness and their utility in high-energy density capacitors. Here, the history of AFEs is reviewed, and the characteristics of antiferroelectricity and the phase transition of an AFE material are described. AFEs are energetically close to ferroelectric (FE) phases, and thus both the electric field strength and applied stress (pressure) influence the nature of the transition. With the comparable energetics between the AFE and FE phases, there can be a competition and frustration of these phases, and either incommensurate and/or a glassy (relaxor) structures may be observed. The phase transition in AFEs can also be influenced by the crystal/grain size, particularly at nanometric dimensions, and may be tuned through the formation of solid solutions. There have been extensive studies on the perovskite family of AFE materials, but many other crystal structures host AFE behavior, such as CuBiP 2 Se 6 . AFE applications include DC-link capacitors for power electronics, defibrillator capacitors, pulse power devices, and electromechanical actuators. The paper concludes with a perspective on the future needs and opportunities with respect to discovery, science, and applications of AFE.

“…According to relevant literature reports, the dielectric peak at low temperature means the phase transition from antiferroelectric1 (AFE1) phase to another antiferroelectric 2 (AFE2); the dielectric peak at high temperature expresses the phase transition from antiferroelectric (AFE2) phase to PE phase [4][5][6]21]. Among them, the phase structure of AFE1 is an orthorhombic phase, while, the AFE2 phase is relatively complex and remains many controversies [6]. At present, there are many kinds of phases considered AFE2, such as tetragonal phase, pseudo-tetragonal phase and rhombohedral phase.…”

In previous work, both Ti‐doped [13] and Sn‐doped [6] PbHfO 3 crystals show excellent FE and antiferroelectric properties due to Sn or Ti doping plays a crucial role in changing properties of PbHfO 3 , especially in structural phase transitions.

PbHfO 3 , a kind of PbBO 3 (B = Ti, Zr and Hf) perovskite oxides, attracts considerable scientific interest for its excellent antiferroelectric properties [4][5][6][7][8][9][10][11]. Therefore, the study of PbHfO 3 has been in the spotlight.…”

Specific heat, dielectric properties, domain structure, and Brillouin light scattering studies in antiferroelectric PbHf1−xSnxO3 single crystals with three different concentrations (x = 0.08, 0.1, and 0.23) are performed in function of temperature. The specific heat and dielectric data reveal clear anomalies at three temperatures denoted as T1, T2, and TC. At T1, transition from the antiferroelectric AFE1 to another antiferroelectric AFE2 phase is realized, the next phase transition (PT) is from AFE2 to an intermediate (IM) phase—at T2, and from IM to paraelectric (PE) phase at TC. PTs at T1 and T2 are definitely of the first order, whereas the PT at TC has features of the second‐order PT. The PT sequences are confirmed by changes in the domain structure. In the PE phase, Brillouin studies reveal the softening and broadening of longitudinal acoustic (LA) mode in the cooling process. The softening and broadening exhibit the maximum values near TC. The transverse acoustic (TA) mode appears near T2. Additional acoustic anomalies are also observed at T1. The temperature dependencies of LA mode indicate the existence of polar regions in PE phase and order–disorder character of the PT at TC. The other PTs are mainly of a displacive character.
