摘要：

Electric-field-induced strain behavior of (1 - x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) (PMNT) crystals with different orientations and compositions was investigated for use as electromechanical actuators. Crystallographically, high strains with low hysteresis were achieved for <001> oriented rhombobedral crystals (29% less than or equal to x less than or equal to 31%) near a morphotropic phase boundary, rather than <110> and <111>. Domain instability could explain inferior strain levels and large hysteresis for <110> and <111> oriented crystals. Ultrahigh strain levels up to 1.8% could be achieved for <001> oriented PMNT crystals, being related to an E-field induced phase transition. - 2 kV/cm negative E-field can be applied to PMNT ferroelectric material with low hysteresis. High strain with low hysteresis makes PMNT crystals promising candidates for high performance solid-state actuators. (C) 2003 Elsevier Science Ltd. All rights reserved.
