摘要：

The representation surfaces of the piezoelectric strain coefficient (d) were calculated for [011], [001], and [111] poled lead magnesium niobate-lead titanate (PMN-PT) crystals with similar to31% PT. It was discovered that the zxt +/- 45degrees cut (rotation around z axis +/- 45degrees) for [011] poled PMN-PT crystal gives a unique repolable shear piezoelectric coefficient d(36) up to 2600 pC/N. The zxt 0degrees cut (without rotation) d(31) up to -1750 PUN was obtained for the [0 11] poled crystals. It was also found that an extraordinarily high shear piezoelectric coefficient d(15) up to 5190 PUN for the single-domain crystal (3 m) occurred in the zxt -22.5 cut (22.5degrees clockwise rotation about the x axis). These calculated results were experimentally verified. (C) 2005 American Institute of Physics.
