摘要：

By using high-pressure heat treatment, we synthesized the single perovskite phase of polycrystalline (1-x)PbZn1/3Nb2/3O3-xPbTiO(3) which was reported to show giant piezoelectricity in crystal forms. Piezoelectric constant of the polycrystalline materials at room temperature was found to become maximum at the rhombohedral side (x = 8%) of morphotropic phase boundary. Microscopic strain under the electric field (E) along different crystallographic directions was identified by observing the x-ray Bragg peak shift of polycrystalline samples with E.
