摘要：

The orientation dependence of piezoelectric properties has been calculated for 0.67Pb(Mn1/3Nb2/3)O-3-0.33PbTiO(3) (PMN-33% PT) single-domain crystals based on the measured full matrix properties. It is found that the maximum d*(33)=2411 pC/N and k*(33)=0.94 occur, respectively, in directions 63.0degrees and 70.8degrees from the spontaneous polarization direction. In [001] of the cubic coordinate, the rotated properties are d*(33)=2316 pC/N and k*(33)=0.93, respectively, comparable to the measured multidomain properties. The results revealed the origin of the superior electromechanical properties in [001] poled PMN-33% PT multidomain crystals as from the large d(15) of the single-domain property.
