Normal piezoelectric coefficient d33, domain structure, and x-ray diffraction of a (001)-cut Pb(In1/2Nb1/2)0.70Ti0.30O3 (PIN-30%PT) single crystal have been investigated as a function of poling electric (E) field. E-field-dependent domain structures were observed by using a polarizing microscope. Piezoelectric coefficient d33 exhibits a rapid increase at E=1–3 kV/cm and reaches a maximum of about 1200 pC/N near E=6 kV/cm. Structural d spacing and domain structure results suggest that polarization rotation from rhombohedral to monoclinic MA phases causes the high piezoelectric response. Overpoling phenomenon associated with a sudden reduction of d33 with increasing field was not evidenced.
