摘要: Using ultrasonic spectroscopy, the frequency dispersions of velocity and attenuation were measured for single crystal 0.72 Pb(Mg1/3Nb2/3)−0.28 PbTiO3 (PMN−28%PT) with engineered domain structures in range 50–110 MHz. We found that dispersion are very small longitudinal wave propagating along [001] pseudotetragonal state. Our results imply developed domain-engineered PMN-PT crystals, which have extremely large d33 k33, great potential high-frequency applications.
