摘要：

The electromechanical properties of rhombohedral single crystals Pb(Mg1/3Nb2/3)-Pb(In1/2Nb1/2)-PbTiO3 (PMN-PIN-PT) were investigated under hydrostatic pressure from 0.1 to 456 MPa. Due to pressure-induced morphotropic phase boundary moving, the piezoelectric coefficients and electromechanical coupling factors of PMN-PIN-PT crystals were found to decrease by similar to 10% and similar to 2%, respectively. The mechanical quality factor Q was found to dramatically decrease, because the domain wall motion and friction between vibrator and pressure-transmitting fluid were enhanced under hydrostatic pressure. On the other hand, the pressure induced depolarization and phase transition were not observed in the experimental pressure range. (C) 2011 American Institute of Physics. [doi:10.1063/1.3622479]
