Piezoresponse force microscopy (PFM) was used to investigate the domain structure of multiferroic BiFeO3-PbTiO3 single crystals with morphotropic phase boundary (MPB) compositions. The PFM data demonstrate the piezoelectricity and the PFM domain responses under the designed experimental setup reveal the coexistence of a rhombohedral, a tetragonal, and an orthorhombic phases in the MPB crystals, which is consistent with the results of structural refinements based on X-ray diffraction data.
利用压电力显微镜(PFM)研究了具有准同型相界(MPB)成分的多铁性BiFeO₃-PbTiO₃单晶的畴结构。PFM数据证明了其压电性,并且在设计的实验装置下PFM畴响应揭示了MPB晶体中菱方相、四方相和正交相的共存,这与基于X射线衍射数据的结构精修结果一致。
