Measurement of all the material properties of PMN-PT single crystals grown by the solid-state-crystal-growth (SSCG) method

This paper is about the characterization of the PMN-32%PT crystals having the symmetry of tetragonal 4mm grown by the SSCG method. All the elastic, piezoelectric, and dielectric constants of the crystals were measured by the resonance method. A total of eleven independent material constants such as six elastic compliance constants at constant electric field, two dielectric constants at constant stress, and three piezoelectric constants were extracted from five sets of crystal samples of different geometries each to have different vibration mode. Validity of the measured data was confirmed through comparison of experimental impedance spectra of the single crystals with numerical impedance spectra calculated with the measured material constants.
