Abstract

In order to find out the origin of the giant piezoelectric effects of relaxor-PbTiO 3 single crystals when poled along nonpolar directions, it is necessary to obtain the complete physical property data of a single domain state. Conventional characterization methods using multiple samples of different geometries often produce inconsistent data set because the domain patterns produced during poling are strongly dependent on the sample geometry. Here, we used the resonant ultrasound spectroscopy (RUS) technique to determine the material constants of a single domain 0.72Pb(Mg 1/3 Nb 2/3 )O 3 -0.28PbTiO 3 single crystal, which has a high mechanical quality factor (Q M ). Errors caused by sample-to-sample variation are avoided because all constants were measured from the same sample. The data set obtained is highly self-consistent, which provides a base for theoretical analysis as well as the input for simulation designs of piezoelectric devices. Comparison with data measured by other methods shows the advantage and higher accuracy of this characterization strategy.
