用分析电子显微镜研究了PbTiO_3-32%PbTiO_3单晶中的磁畴结构。聚束电子衍射和穿透聚焦高分辨像序列分析表明，MB相是由71°菱面体纳米微区组成的自适应相，纳米磁区壁平行于{110}面。这些结果表明并支持了MA相也可能是由109°菱面体纳米微区组成的适应性相的观点，该纳米微区的磁畴壁平行于{001}面。
The domain structure in Pb(Mg1/3Nb2/3)O3–32%PbTiO3 single crystal has been investigated with analytical electron microscopy. It is revealed that the MB phase is an adaptive phase composed of 71° rhombohedral nanodomains and that the nanodomain walls are parallel to {110} planes by a combination of convergent beam electron diffraction and through-focus high-resolution image series. The findings suggest and are supportive of the viewpoint that the MA phase could also be an adaptive phase composed of 109° rhombohedral nanodomains with domain walls parallel to {001} planes.
