A simplified mode of differential phase contrast Lorentz microscopy for the study of magnetic domain structures in thin films is proposed and demonstrated. This mode employs a single annular detector in a scanning transmission electron microscope rather than the specialized split detectors that have been previously used. The resulting signal is sufficiently linear with magnetic field strength to allow quantitative data to be obtained on the domain configurations and the natures of the domain walls.
提出并演示了一种用于研究薄膜磁畴结构的简化微分相衬洛伦兹显微镜模式。该模式在扫描透射电子显微镜中采用单个环形探测器，而不是先前使用的专门的分裂探测器。所得信号与磁场强度具有足够的线性关系，从而能够获取有关磁畴结构和畴壁性质的定量数据。
