Using ultrasonic spectroscopy, the frequency dispersions of ultrasonic velocity and attenuation were measured for single crystal 0.72Pb(Mg 1/3Nb2/3)-0.28PbTiO3 (PMN-28%PT) with engineered domain structures in the frequency range of 50-110 MHz. We found that the velocity dispersion and attenuation are very small for the longitudinal wave propagating along [001] of the pseudotetragonal state. Our results imply that the developed domain-engineered PMN-PT single crystals, which have extremely large d33 and k33, have great potential for high-frequency applications.
