This is indicated by typical relaxor characteristics such as a transition to the global pseudocubic phase, a constriction in the FE hysteresis loop, and a sudden decrease in the negative strain accompanied by an increase in maximum strain. Most notably, with a further increase in x (>0.05), ...
> Thanks again for a sight full of great info. Your input helped me a great deal with a small tank project, a 55 gal. acrylic. I ripped out the little 4"x4" corner skimmer box and replaced it with a larger one that spans most of the back wall. Punched in two 1 1/2" drain l...
It is demonstrated that macroscopic strain of 0.66PNN-0.34PT stems mainly from intrinsic structure. The present study provides evidence for the relationship between microstructure and macroscopic properties, which is beneficial to the design of new materials with piezoelectric properties....
In addition, strain asymmetry 纬_S and internal bias field E_(bias) of PNN-PT-glycerol are much less than those of PNN-PT. However, the ferroelectric properties can be recovered by bipolar cycles and thermal annealing; and such recovery is much easier and larger in PNN-PT-glycerol than ...
