Domain walls are the interfaces between domains with different magnetic orientations. They carry essential information on the magnetic nanostructure and can have distinct topological properties. Intensive research has been carried out on magnetic domains. However, the study and direct control of individual domain walls remain challenging due to the need for extremely pure materials and very specific experimental protocols.
Using Scanning NV Magnetometry, the group led by Prof. Patrick Maletinksy (University of Basel) unveiled for the first time the nanoscale mechanics of antiferromagnetic domain walls in chromium oxide….
