The E-O coefficients of the 0.67PMN-0.33PT single crystals were r(333) = 107 pm/V at room temperature and 950 pm/V at 80 degrees C. The piezoelectric coefficient d(311) of the 0.67PMN-0.33PT single crystals increased from 45 pC/N at room temperature to 1015 pC/N at 80 degrees C. Large E-O and piezoelectric coefficients at 80 degrees C were from the engineering domain configuration induced by a transition from the rhombohedral phase othorhombic phase.
