Abstract

Pb(In(12)Nb(12))O(3)-Pb(Mg(13)Nb(23))O(3)-PbTiO(3) (PIN-PMN-PT) single crystals have been developed recently, which can increase the operating temperature by at least 20 degrees C compared to PMN-PT crystals. We have measured a complete set of material properties of single domain PIN-PMN-PT crystal, which is urgently needed in theoretical studies and electromechanical device designs using this crystal. Because the rotated values of d33*=1122 pCN and k33*=89% along 001 calculated using the single domain data obtained here are in good agreement with the 001 poled multidomain PIN-PMN-PT crystals, one may conclude that the physical origin of the ultrahigh piezoelectric properties mainly come from orientation effect.

摘要

铅铟铌酸盐-铅镁铌酸盐-钛酸铅(PIN-PMN-PT)单晶最近已被研发出来,与PMN-PT晶体相比,其工作温度可至少提高20摄氏度。我们已经测量了单畴PIN-PMN-PT晶体的全套材料特性,这在使用该晶体的理论研究和机电设备设计中是迫切需要的。由于使用此处获得的单畴数据计算得出的沿001方向的d33旋转值为1122 pCN,k33旋转值为89%,与001极化的多畴PIN-PMN-PT晶体吻合良好,因此可以得出结论,超高压电特性的物理起源主要来自取向效应。
