Using combined resonance and ultrasonic methods, a full set of material constants has been measured for morphotropic phase boundary (MPB) composition xPb (In1/2 Nb1/2) O3 - (1-x-y) Pb (Mg 1/3 Nb2/3) O3 -y PbTiO3 (PIN-PMN-PT) single crystals poled along [001] c. Compared with the MPB composition (1-x) Pb (Mg1/3 Nb2/3) O3 -x PbTiO3 (PMN-PT) single crystals, the PIN-PMN-PT single crystals have smaller anisotropy, higher Curie temperature (Tc ≈197 °C), and higher rhombohedral to tetragonal phase transition temperature (TR-T ≈96 °C). The electromechanical properties obtained here are the best found so far for this ternary system with d33 ≈2742 pC/N, d31 ≈-1337 pC/N, k33 ≈95%, and k31 ≈65%.
