Deciphering the atomic-scale structural origin for large dynamic electromechanical response in lead-free Bi0.5Na0.5TiO3-based relaxor ferroelectrics [PDF]

Nature Communications, 2022
For relaxor ferroelectrics, correlating their properties and local structures is challenging. Here, the authors correlate the atomic-scale structure and the large dynamic electromechanical property in Bi0.5Na0.5TiO3-based relaxor ferroelectrics.

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 ...

Barkhausen Noise in a Relaxor Ferroelectric [PDF]

, 2001
Barkhausen noise, including both periodic and aperiodic components, is found in and near the relaxor regime of a familiar relaxor ferroelectric, PbMg$_{1/3}$Nb$_{2/3}$O$_3$, driven by a periodic electric field.

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
