摘要：

Surface acoustic wave propagation in a 0.955Pb (Zn1/3Nb2/3)O-3-0.045PbTiO(3) multidomain single crystal poled along [001](c) has been analyzed theoretically using Christoffel wave equations. From the measured experimental data, the orientational dependence of surface acoustic wave phase velocities, electromechanical coupling coefficients and power flow angles was calculated. The results showed that surface acoustic wave propagations of 0.955Pb (Zn1/3Nb2/3)O-3-0.045PbTiO(3) are poor than 0.93Pb(Zn1/3Nb2/3)O-3-0.07PbTiO(3) crystal slightly. However, the 0.955Pb (Zn1/3Nb2/3)O-3-0.045PbTiO(3) single crystals have higher rhombohedral-tetragonal phase transition temperature and much stabler electromechanical properties. This may expand applications range of SAW devices.
