Scientists observe a new type of topological defect in chiral magnets for the first time

'Topological defects' are formed when the symmetry of a magnetic material is disrupted. Domain walls (DWs) are a type of topological defect that separates regions of different magnetic orientations. A widely studied phenomenon, ...
