Lorentz Scanning Transmission Electron Microscopy (STEM) technique has emerged as a powerful tool for studying complex magnetic topologies with nanoscale precision. By leveraging advances in electron optics, including aberration correction and phase imaging, corrected Lorentz STEM provides enhanced spatial resolution and contrast, allowing researchers to observe magnetic domains, skyrmions, vortices, and other topological structures. 

Traditional Lorentz microscopy, while effective for visualizing magnetic structures, has limitations in spatial resolution and sensitivity, especially for weak magnetic signals. Corrected Lorentz STEM overcomes these resolution challenges, allowing us to probe magnetic topologies never before possible. The technique offers a promising pathway for advancing our understanding of magnetic materials, with implications for data storage, quantum computing, and magnetic sensor technology. The talk will focus on the magnetic topologies within multiferroic Aurivillius thin films and ferromagnetic Fe3Sn single crystals.
