用同步辐射X射线衍射研究了赝立方相0.3BaTiO_3 -0.1Bi（Mg_（1/2）Ti_（1/2））O_3 - 0.6BiFe_（3）陶瓷在外加电场作用下的压电响应。从110、111和200伪立方衍射峰确定的所有晶格应变显示出类似的晶格应变滞后，其与本体蝶状应变曲线相当。结果表明，晶格应变的滞后和各向异性的缺乏与复杂的畴结构和相界成分有关。
Contributions to the piezoelectric response in pseudocubic 0.3BaTiO3-0.1Bi(Mg1/2Ti1/2)O3-0.6BiFeO3 ceramics were investigated by synchrotron X-ray diffraction under electric fields. All of the lattice strain determined from the 110, 111, and 200 pseudocubic diffraction peaks showed similar lattice strain hysteresis that was comparable to the bulk butterfly-like strain curve. It was suggested that the hysteresis of the lattice strain and the lack of anisotropy were related to the complex domain structure and the phase boundary composition.
