Dielectric Behavior of PFW-PT Relaxors: Model-Parameters Extraction

In this paper, we systematically present the physical and mathematical meanings of the parameters used in Burfoot et al.'s and Eiras et al.'s model. Based on our experimental results in (l-x)PFW-xPT relaxor system and the theoretically modelling results, it is shown that the parameter valu...

Summary:In this paper, we systematically present the physical and mathematical meanings of the parameters used in Burfoot et al.'s and Eiras et al.'s model. Based on our experimental results in (l-x)PFW-xPT relaxor system and the theoretically modelling results, it is shown that the parameter values in Burfoot et al.'s model and Eiras et al.'s model have not any variations after normalizing the maximum dielectric constant and shifting the temperature of the maximum dielectric constant Tm. It is also shown that the parameters in Eiras et al.'s model have better physical and mathematical meanings.
