Description	Journal: Japanese Journal of Applied Physics The piezoelectric properties of a $Pb[(Zn_{1/3}Nb_{2/3})_{0.91}]Ti_{0.09}O_{3}$ binary system single crystal oriented along the [001] direction in the rhombohedral phase was investigated under pressures up to 500 MPa at 25°C. With increasing hydrostatic pressure, the change of the resonance and antiresonance frequency characteristic curves of the impedance and phase from sharp to broad ones was observed. The resonance frequency f$ _{r}$ increased, while the antiresonance frequency f$ _{a}$ remained almost constant. The electromechanical coupling coefficient in the $k_{31}$ mode decreased markedly with pressure, and the value of the k$ _{31}$ mode decreased by 18% at 500 MPa. The electromechanical coupling coefficient in the k$ _{33}$ mode decreased slightly with pressure. The value of the k$ _{33}$ mode decreased slightly by only 3% at 500 MPa. The large decrease in the k$ _{31}$ value with pressure exhibited a marked contrast with the slight decrease in the k$ _{33}$ value with pressure. The changes in the values of the elastic compliances s$ _{11} ^{E}$ and s$ _{33} ^{E}$ with pressure were observed to be large from the changes in f$ _{r}$ and f$ _{a}$ with pressure. s$ _{11} ^{E}$ and s$ _{33} ^{E}$ at 400 MPa were estimated to be 7.23 and $13.95×10^{-11}$ $m^{2}$/N, respectively. The large k$ _{31}$ in the k$ _{31}$ mode is considered to be due to the mechanical softness of the PZN-PT(91/9) single crystal. On the other hand, the slight decrease in k$ _{33}$ with pressure is thought, on the basis of the engineered domain concept, to be due to the stable domain configuration responsible for the longitudinal k$ _{33}$ mode.
