Liquid-matter relaxor ferroelectrics by design
Nature CommunicationsKnowing that traditional relaxor ferroelectrics stem from crystalline materials, one may ask whether they stabilize the liquid-matter analogy. The perspective is challenging and may enable a generic design of fluidic and flexible relaxor ferroelectrics ...

Evolution of dielectric and ferroelectric relaxor states in Al3+-doped BaTiO3
AIP Advances, 2015 In ferroelectric BaTiO3, we report the evolution of the Dielectric Relaxor and Ferroelectric Relaxor states as a function of B-site doped Al3+ concentration. The relaxor states occur after the paraelectric-ferroelectric phase transition upon cooling. Two

AgNb7O18: An Ergodic Relaxor Ferroelectric [PDF]
Inorganic Chemistry, 2014 Abstract AgNb7O18 is a relaxor ferroelectric with a Burns temperature of ∼490 K and an incipient transition to the nonergodic state. The short-range structure is shown by convergent-beam electron diffraction to have the polar space group Im2m, but refinements against powder X-ray diffraction find the long-range structure to have the ...

Ferroelectric-to-relaxor crossover in Sb doped PLZT x/52/48 (2 ≤ x ≤ 16) piezoelectric ceramics
Journal of Asian Ceramic Societies, 2014 Dielectric behavior and diffuse phase transition have been investigated in Sb doped lead lanthanum zirconate titanate (PLZT) ceramics to understand the role of La and Sb in ferroelectric-to-relaxor crossover.

Ferroelectric Relaxor Quantum Crystals [PDF]
Crystals, 2018 A discussion is given of ferroelectrics (FEs) that have their Curie temperatures Tc very near absolute zero. These have differences in their dynamics in comparison with higher-temperature systems, since domain wall motion occurs via quantum mechanical ...

Theory of relaxor-ferroelectricity [PDF]
Scientific Reports, 2020 AbstractRelaxor-ferroelectrics are fascinating and useful materials, but the mechanism of relaxor-ferroelectricity has been puzzling the scientific community for more than 65 years. Here, a theory of relaxor-ferroelectricity is presented based on 3-dimensional-extended-random-site-Ising-model along with Glauber-dynamics of pseudospins. We propose a new

Dielectric and electro-mechanic nonlinearities in perovskite oxide ferroelectrics, relaxors, and relaxor ferroelectrics [PDF]
Journal of Applied Physics, 2021 The polarization and strain response of ferroelectric materials at electric fields below the macroscopic coercive field is of paramount importance for the operation of many electronic devices. The response of real ferroelectric and related materials is, in general, complex and difficult to interpret.
