Creation and observation of Hopfions in magnetic multilayer systems
In three dimensions, magnetic Skyrmions can form extended strings. By connecting the ends of a Skyrmionic string, a magnetic Hopfion is formed. Here, the authors present experimental evidence for the appearance of Hopfions, a topological soliton defined by a Hopf number, in a magnetic system.
