Abstract

The clastic, piezoelectric, and dielectric properties of a 0.955Pb(Zn1/3Nb2/3)O3-0.045PbTiO3 (PZN4.5%PT) multi-domain single crystal, poled along [001] of the original cubic direction, have been determined experimentally using combined resonance and ultrasonic methods. At room temperature, the PZN-4.5%PT single crystal has rhombohedral symmetry. After being poled along [001], four degenerate states still remain. Statistically, such a domain-engineered crystal may be treated as having an average tetragonal symmetry, and its material constants were determined based on 4 mm symmetry. It was confirmed that the electromechanical coupling coefficient fcss for the domain-engineered samples is >90%, and the piezoelectric constant daa is >2000 pC/N. A soft shear mode with a velocity of 700 m/s was found in the [110] direction. Erom the measured experimental data, the orientational dependence of phase velocities and electromechanical coupling coefficients was calculated. The results showed that the transverse and longitudinal coupling coefficients, feai and fess, reach their maximum along [110] and [001], respectively.
