Lead‐Free Relaxor Ferroelectrics

Journal of the American Ceramic Society, 2011
Feature size is a natural determinant of material properties. Its design offers the technological perspectives for material improvement. Grain size, crystallite size, domain width, and structural defects of different nature constitute the classical design elements.

Relaxor ferroelectric transducers

IEEE Symposium on Ultrasonics, 2002
Novel ultrasonic transducers whose sensitivity can be controlled with a DC bias field have been developed by utilizing relaxor ferroelectrics as a transducer material in place of conventional piezoelectrics. Relaxor ferroelectrics have a large bias-field-induced piezoelectricity as well as a giant electrostrictive effect due to their extremely large ...

Relaxor ferroelectric materials

IEEE Symposium on Ultrasonics, 2002
The authors review relaxor ferroelectrics and associated phenomena. It is noted that the anomalously large dielectric constants (K) of relaxor ferroelectrics make them ideal for multilayer capacitors, electrostrictive actuators, and E-field-induced piezoelectrics for low-frequency sonar and high-frequency biomedical transducers.

Relaxor ferroelectric polymers

ISAF 1998. Proceedings of the Eleventh IEEE International Symposium on Applications of Ferroelectrics (Cat. No.98CH36245), 2002
An exceptionally high electrostrictive response was observed in electron irradiated polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) copolymer. Moreover, the transverse strain of the material can be tuned over a large range by different sample treatment conditions.

Optical Properties of Relaxor Ferroelectrics

Ferroelectrics, 2004
The optical absorption spectrum, luminescent emission and photoconductivity were investigated in single crystal PbMg1/3Nb2/3O3 and in the Pb0.91La0.09(Zr0.65Ti0.35)O3 ceramics in the wide temperature region. The spectrum of the luminescence correlates with spectrum of photoconductivity emission.
