Liquid-matter relaxor ferroelectrics by design [PDF]
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 ...

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 ...

Polarization Reversal Via a Transient Relaxor State in Nonergodic Relaxors Near Freezing Temperature [PDF]
SSRN Electronic Journal, 2018 Among the unresolved issues in the study of relaxor ferroelectrics is the role of freezing temperature, across which the dynamics of polarization reversal in relaxor ferroelectrics changes. The presence of this freezing temperature is best manifested by the appearance of a double polarization hysteresis loop just above the freezing temperature.

Achieving Temperature‐Insensitive High Piezoelectricity by Reentrant Relaxor Transition [PDF]
Advanced ScienceAlthough precision sensors and actuators demand piezoelectric materials with temperature‐insensitive high piezoelectricity (d33), achieving such a property is physically challenging because high d33 relies on tuning the material to the vicinity of a ...

Dynamics of relaxor ferroelectrics [PDF]
Physical Review B, 2000 We study a dynamic model of relaxor ferroelectrics based on the spherical random-bond---random-field model and the Langevin equations of motion. The solution to these equations is obtained in the long-time limit where the system reaches an equilibrium ...

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
