Critical state to achieve a giant electric field-induced strain with a low hysteresis in relaxor piezoelectric ceramics

Journal of Materiomics, 2021
Due to the extrinsic contribution of domain wall motions to electro-strains, the incompatibility of the large electro-strain with a low hysteresis in piezoelectric ceramics is a stumbling block for designing high-performance piezoelectrical actuators ...

Barkhausen Noise in a Relaxor Ferroelectric [PDF]

Physical Review Letters, 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. The temperature dependences of both the amplitude and spectral form show that the size of the coherent dipole moment changes shrink as the ...

Semiconductor/relaxor 0–3 type composites: A novel strategy for energy storage capacitors

Journal of Science: Advanced Materials and Devices, 2021
We report a novel strategy to enhance the dielectric breakdown strength and the energy storage performance of lead-free relaxor ferroelectric ceramics through the fabrication of semiconductor/relaxor 0–3 type composites based on 0.6Ba(Zr0.2Ti0.8)O3-0.4 ...

Giant electrocaloric effect in the thin film relaxor ferroelectric 0.9 PbMg1/3Nb2/3O3–0.1 PbTiO3 near room temperature. [PDF]

, 2006
We have recently observed a giant electrocaloric effect (12 K in 25 V) in 350 nm sol-gel PbZr0.95Ti0.05O3 films near the ferroelectric Curie temperature of 242oC.
