ABSTRACT
In order to better utilize the superior transverse piezoelectric properties of [011] poled (1-x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 single crystals with the composition near the morphotropic phase boundary, a complete set of elastic, dielectric, and piezoelectric constants of [011] poled 0.71Pb(Mg1/3Nb2/3)O3–0.29PbTiO3 single crystal was measured by ultrasonic and resonance methods at room temperature. The electromechanical coupling coefficient k32 and transverse piezoelectric constant d32 can reach 0.94 and -1883 pC/N, respectively. This complete set of material properties will provide convenience for device designs and fundamental theoretical studies.
