Antiferroelectrics: History, fundamentals, crystal chemistry, crystal structures, size effects, and applications

TL;DR: Antiferroelectric (AFE) materials are of great interest owing to their scientific richness and their utility in high energy density capacitors as discussed by the authors, and the characteristics of AFE and the phase transition of an AFE material are described.

Field-induced antiferroelectric-ferroelectric phase transitions in the Pb0.98La0.02(Zr0.70Hf0.30)(1-x)TixO3 system

TL;DR: In this article, a phase transition between the antiferroelectric AFE (II) phase and the ferroelectric phase was investigated in the Pb0.98La0.02(Zr0.70Hf0.30)TixO3 system.

Anomalous dielectric behaviour during the monoclinic to tetragonal phase transition in La(Nb0.9V0.1)O4

TL;DR: In this article, an anomalous decrease in relative permittivity at TM-T is predicted from the Clausius-Mosotti relation and Shannon's additive rule, which has not previously been observed in linear dielectrics and may aid in the design of novel microwave dielectric composites.

Symmetry-determined antiferroelectricity in PbZr O 3 , NaNb O 3 , and PbHf O 3

TL;DR: In this article, a theoretical analysis of the complex phase transitions in the perovskite compounds of antiferroelectric and ferroelastic phase transitions is presented, and the symmetry-breaking order parameters associated with the transitions in these compounds are determined.
Journal ArticleDOI

Crystallographic and optical study of PbHfO3 crystals

TL;DR: The use of birefringence imaging microscopy and high-resolution X-ray diffraction for determining the symmetries of the phases in PbHfO3 between room temperature and 870 K is detailed.

Pressure and Temperature Dependence of the Dielectric Properties and Phase Transitions of the Antiferroelectric Perovskites: PbZr O 3 and PbHf O 3

TL;DR: In this paper, the authors showed that there are two independent low-frequency temperature-dependent lattice vibrational modes in PbZr${\mathrm{O}}_{3}$: a ferroelectric (FE) mode which determines the large polarizability and the Curie-Weiss behavior of the static dielectric constant in the paraelectric phase, and an AFE mode (probably a coupled mode) which causes the AFE transition.
