Heterogeneous field response of hierarchical polar laminates in relaxor ferroelectrics [PDF]

Science, 2023
Understanding the microscopic origin of the superior electromechanical response in relaxor ferroelectrics requires knowledge not only of the atomic-scale formation of polar nanodomains (PNDs) but also the rules governing the arrangements and stimulated ...

Liquid-matter relaxor ferroelectrics by design [PDF]

Nature Communications
Knowing 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 tunneling and not by thermally activated diffusion.

The generalized Vogel-Fulcher-Tamman equation for describing the dynamics of relaxor ferroelectrics. [PDF]

Sci Rep, 2019
Relaxor ferroelectrics (RF) are outstanding materials owing to their extraordinary dielectric, electromechanical, and electro-optical properties. Although their massive applications, they remain to be one of the most puzzling solid-state materials ...

Non-steady-state optothermal electromotive force in relaxor ferroelectrics [PDF]

Scientific Reports
We predict a new non-steady-state optothermal electromotive force effect in relaxor ferroelectrics. The effect is observed and studied in a PbNi $$_{1/3}$$ Ta $$_{2/3}$$ O $$_3$$ crystal at light wavelength $$\lambda =532$$ nm and room temperature, which
