Deciphering the atomic-scale structural origin for large dynamic electromechanical response in lead-free Bi_0.5Na_0.5TiO₃-based relaxor ferroelectrics. [PDF]

Nat Commun, 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.

Titanate-based high-entropy perovskite oxides relaxor ferroelectrics. [PDF]

Sci Rep
Different combinations of monovalent and trivalent A-cations in high-entropy perovskite oxides (HEPOs) were investigated. The multicomponent (A′0.2A″0.2Ba0.2Sr0.2Ca0.2)TiO3 (A′ = Na+, K+, A″ = Bi3+, La3+) perovskite compounds were successfully ...

Piezoelectric response of disordered lead-based relaxor ferroelectrics

Communications Materials, 2023
Lead-based relaxor ferroelectrics are known for their large piezoelectric response, but the relation between the response and the nanoscale structure of these materials is still under debate. In this Perspective, the microscopic implications of the polar

Coexistence of the Critical Slowing Down and Glassy Freezing in Relaxor Ferroelectrics [PDF]

, 1999
We have developed a dynamical model for the dielectric response in relaxor ferroelectrics which explicitly takes into account the coexistence of the critical slowing down and glassy freezing.

Dielectric nonlinearity of relaxor ferroelectric ceramics at low ac drives [PDF]

, 2000
Dielectric nonlinear response of (PbMg$_{1/3}$Nb$_{2/3}$O$_3$)$_{0.9}$(PbTiO$_3$)$_{0.1}$ (0.9PMN-0.1PT) relaxor ceramics was investigated under different ac drive voltages. It was observed that: (i) the dielectric permittivity is independent on ac field

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.
