Abstract

The effect of dc bias electric field on the hydrostatic piezoelectric coefficient dh in Lead Zinc Niobate-Lead Titanate (PZN:PT) single crystal solid solutions in the vicinity of the morphotropic phase boundary (MPB) is studied. The hydrostatic measurements can be very important to gain insight into these materials. In particular, the discrepancy between sum of piezoelectric coefficients d33 + 2 d31 vs. hydrostatic dh coefficient measured directly suggests the importance of extrinsic contributions. Limiting values of measured hydrostatic piezoelectric coefficients dh for high electric fields are compared with calculated theoretic values from the Landau-Devonshire-Ginzburg (LCD) phenomenological theory. The influence of complicated microstructure within the single domain region is studied. Such microstructure could possibly account for the inability of the LCD phenomenology to give correct electric field bias dependence of dielectric constant.
