Using combined resonance and ultrasonic methods, a full set of material constants has been measured for morphotropic phase boundary (MPB) composition xPb(In(12)Nb(12))O(3)-(1-x-y)Pb(Mg(13)Nb(23))O(3)-yPbTiO(3) (PIN-PMN-PT) single crystals poled along 001. Compared with the MPB composition (1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3) (PMN-PT) single crystals, the PIN-PMN-PT single crystals have smaller anisotropy, higher Curie temperature (T(c) approximately 197 degrees C), and higher rhombohedral to tetragonal phase transition temperature (T(R-T) approximately 96 degrees C). The electromechanical properties obtained here are the best found so far for this ternary system with d(33) approximately 2742 pCN, d(31) approximately -1337 pCN, k(33) approximately 95%, and k(31) approximately 65%.
采用共振和超声相结合的方法，对沿001极化的准同型相界（MPB）成分xPb(In(12)Nb(12))O(3)-(1-x-y)Pb(Mg(13)Nb(23))O(3)-yPbTiO(3)（PIN-PMN-PT）单晶测量了全套材料常数。与MPB成分(1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3)（PMN-PT）单晶相比，PIN-PMN-PT单晶具有较小的各向异性、较高的居里温度（Tc约197℃）和较高的菱方相到四方相转变温度（TR-T约96℃）。这里得到的机电性能是迄今为止在该三元体系中发现的最佳性能，d(33)约2742 pCN，d(31)约-1337 pCN，k(33)约95%，k(31)约65%。
