摘要：
The electrical properties and polarization fatigue of [001]-oriented 6Pb(Sc1/2Nb1/2)O-3-70Pb(Mg1/3Nb2/3)O-3-24PbTiO(3) (6PSN-70PMN-24PT) crystals were investigated. Compared with binary Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMN-PT) crystals, the ternary 6PSN-70PMN-24PT crystal showed a higher rhombohedraltetragonal transition temperature (TR-T=120 degrees C) and a larger coercive field (E-c=4kV/cm). It was found that the piezoelectric constant (d(33)approximate to 1200pC/N) and electromechanical coupling coefficient (k(t)approximate to 61%) were weakly dependent on the thermal annealing temperature (T-a), maintaining over 90% of the original value at T-a<120 degrees C, indicating excellent piezoelectric thermal stability. Electric fatigue measurements showed that the ternary 6PSN-70PMN-24PT crystal exhibited slight fatigue characteristics below 10(5) bipolar cycles, while the binary PMN-PT crystal exhibited sudden polarization degradation when the cycle numbers were above 10(2) cycles. The improved fatigue stability for 6PSN-70PMN-24PT crystals was attributed to the large coercive field. The physical mechanisms of the enhanced coercive field and high transition temperature were discussed based on repulsive energy and polar domains.
