Creation and observation of Hopfions in magnetic multilayer systems

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.
