Zusammenfassung

The vortex state, characterized by a curling magnetization, is one of the equilibrium configurations of soft magnetic materials1, 2, 3, 4 and occurs in thin ferromagnetic square and disk-shaped elements of micrometre size and below. The interplay between the magnetostatic and the exchange energy favours an in-plane, closed flux domain structure. This curling magnetization turns out of the plane ...
