报告摘要： A review will be given on the analysis of magnetic microstructure, demonstrating how magnetic domains and their substructures can in general be analysed based on a combination of micromagnetism, domain theory and experimental observation by magneto-optical Kerr microscopy. For the latter, recent developments in wide-field Kerr microscopy will be introduced, including depth-sensitive and time-resolved domain imaging, a mathematical deconvolution method to enhance the lateral resolution, contrast separation and -enhancement by using a novel light-emitting diode (LED) lamp, as well as vector magnetometry and in-situ quantitative Kerr microscopy of complete magnetization processes.
