Abstract

The elastic, piezoelectric, and dielectric constants of 0.67Pb(Mg_1/3Nb_2/3)O₃-0.33PbTiO₃ domain engineered single crystal were determined experimentally by using ultrasonic and resonance methods. It was confirmed that the single crystal system has large electromechanical coupling coefficient k₃₃ (∼94%) and piezoelectric constant d₃₃ (∼2800 pC/N) if the poling is done along the [001] of pseudocubic directions. A soft shear mode with a velocity of 880 m/s was observed in the [110] direction with displacement in [110]. Using the measured data, the orientation dependence of phase velocities and electromechanical coupling coefficients were calculated. The origin of experimental errors and their influence on measured results are also examined.
