ABSTRACT
The orientation dependence of piezoelectric properties has been calculated for 0.67Pb(Mn[sub ⅓]Nb[sub 2/3])O[sub 3]-0.33PbTiO[sub 3] (PMN-33%PT) single-domain crystals based on the measured full matrix properties. It is found that the maximum d[sup *, sub 33]=2411 pC/N and k[sup *, sub 33]=0.94 occur, respectively, in directions 63.0° and 70.8° from the spontaneous polarization direction. In [001] of the cubic coordinate, the rotated properties are d[sup *, sub 33]=2316 pC/N and k[sup *, sub 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[sub 15] of the single-domain property.
