Pb(In(0.5)Nb(0.5))O(3)-Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) (PIN-PMN-PT) ferroelectric crystals attracted extensive attentions in last couple years, due to their higher usage temperatures range ( > 30 degrees C) and coercive fields (similar to 5 kV/cm), meanwhile maintaining similar electromechanical couplings (k(33) >90%) and piezoelectric coefficients (d(33) similar to 1500 pC/N), when compared to their binary counterpart Pb(Mg(1/3)Nb(2/3))O(3-)PbTiO(3). In this article, we reviewed recent developments on the PIN-PMN-PT single crystals, including the Bridgman crystal growth, dielectric, electromechanical, piezoelectric and ferroelectric behaviors as functions of temperature and dc bias. Mechanical quality factor Q was studied as a function of orientation and phase. Of particular interest is the dynamic strain, which related to the Q and d(33), was found to be improved when compared to the binary system, exhibiting the potential usage of PIN-PMN-PT in high power application. Furthermore, PIN-PMN-PT crystals exhibit improved thickness dependent properties, due to their small domain size, being on the order of 1 mu m. Finally, the manganese acceptor dopant in the ternary crystals was investigated and discussed briefly in this paper. (C) 2010 Elsevier B.V. All rights reserved.
