报道了 (011) [Pb(Mg1/3Nb2/3)O-3]((1-x))-[PbTiO3](x) (PMN-PT, x 近似于 0.32) 单晶的铁电性能，重点关注压电应变响应。通过适当地从去极化方向反转电场来实现两个巨大的可逆且稳定的残余应变状态和可调谐的残余应变特性。独特的压电应变响应，特别是沿[100]方向，主要源于菱面体相晶体结构中的非180度铁电极化重新取向。这种具有可调残余应变特性的巨大应变磁滞可能对基于磁电的存储器件以及其他应用的潜在候选者有用。 (c) 2011 年美国物理研究所。 [doi:10.1063/1.3595670]
The ferroelectric properties of (011) [Pb(Mg1/3Nb2/3)O-3]((1-x))-[PbTiO3](x) (PMN-PT, x approximate to 0.32) single crystals with focus on piezoelectric strain response were reported. Two giant reversible and stable remanent strain states and tunable remanent strain properties are achieved by properly reversing the electric field from the depolarized direction. The unique piezoelectric strain response, especially along the [100] direction, mainly stems from the non-180 degrees ferroelectric polarization reorientation in the rhombohedral phase crystal structure. Such giant strain hysteresis with tunable remanent strain properties may be useful for magnetoelectric based memory devices as well as a potential candidate for other applications.
