The frequency dispersion of ultrasonic velocity and attenuation in [001]c-poled 0.24Pb(In1/2Nb1/2)O3-0.45Pb(Mg1/3Nb2/3)O3-0.31PbTiO3 (PIN-0.45PMN-0.31PT) ternary single crystal were measured by ultrasonic spectroscopy from 25 to 100 MHz for the longitudinal wave. It was found that the velocity has a linear relationship with the frequency f, but the attenuation has a quadratic relation with f. The attenuation and frequency dispersion of the ternary system are lower than that of the (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) binary system and the coercive field also increased by a factor of 2.5, hence, the ternary single system is superior to the corresponding binary single-crystal system for high-frequency and high-power transducer applications.
