The domain structure in PLZT (6-8)/65/35 and spontaneous ferroelectric-relaxor phase transition
1995
Abstract In order to test the hypothesis proposed in Reference 10 about a spontaneous relaxor-ferroelectric phase transition in PLZT (6-7)/65/35 the hysteresis loops and domain structure measurements were carried out. The results confirm this hypothesis. The appearance of the ferroelectric long range order in PLZT with decreasing concentration of La ions is explained by a larger coupling between the feroelectrically active BO6 octahedrons due to smaller concentration of defects and higher dielectric constant.
Dielectric Properties of PbSc1/2Nb1/2O3-PbTiO3Ceramics
2004
Lead titanate solid solutions exhibits extreme values of some physical parameters. We have investigated a ferroelectric relaxor ceramics of PSN-PT composition near the morphotropic phase boundary. Results are discussed with account for the relaxor properties related to defects and disordering of the PSN-PT system.
Low and Infra-Low Frequency Measurements in Lead Titanate Solid Solutions
2006
The study of PSN-PT ferroelectric relaxor ceramics exhibiting extreme values of some physical parameters near the morphotropic phase boundary is reported. The results are discussed to account for the relaxor properties related to defects and disordering of the PSN-PT system.
