用压电响应力显微镜和透射电子显微镜研究了88%PbTiO_3(Zn1/3Nb_2/3)O_3-12%PbTiO_3(用聚焦离子束球磨)单晶片的磁区微结构。已经注意到从驰豫材料典型的斑驳微结构到铁电材料典型的更大尺度的磁畴的戏剧性变化。与衬底夹持相关的应力被怀疑是从短程到长程极性有序转变的原因，类似于通过热淬火实现的阳离子有序所引起的影响。
Domain microstructures in single crystal lamellae of 88%Pb(Zn1/3Nb2/3)O3-12%PbTiO3 (cut from bulk using focused ion beam milling) have been mapped using both piezoresponse force microscopy and transmission electron microscopy. Dramatic changes from mottled microstructures typical of relaxors to larger scale domains typical of ferroelectrics have been noted. Stresses associated with substrate clamping are suspected as the cause for the transition from short- to long-range polar order, akin to effects induced by cation ordering achieved by thermal quenching.
