  Prof. Fengshan Zheng is dedicated to the methodological development and application of electromagnetic field imaging using advanced transmission electron microscopy, and has made a list of achievements: 1) experimentally discovered a new type of topological magnetic texture—magnetic bobber; 2) experimentally discovered magnetic antiskyrmions in isotropic chiral magnets, and realized magnetic skyrmion-antiskyrmion pair and its annihilation; 3) experimentally identified a novel type of interaction between skyrmions—braiding, forming a novel type of three-dimensional topological magnetic structure—skyrmion braids; 4) developed quantitative high-resolution magnetic imaging, enabling the determination of local (boundary) magnetization in nanostructures. So far, 37 SCI papers have been published; 16 papers as the first/corresponding author, including Nature Nanotechnology, Nature Physics, Physical Review Letters, Nature Communications, Journal of the American Chemical Society and Nano Letters.
