Magnetic vortex-topological soliton in a ferromagnet with an easy-axis anisotropy
Kovalev A.S. , Kosevich A.M., Maslov K.V.
A bound, multimagnon state with nonvanishing angular momentum is examined in terms of the Landau-Lifshits equation without damping. It is shown that such a magnetic vortex is associated with a linear topological peculiarity. The characteristics of this vortex are obtained with the help of a computer in a wide range of precessional frequencies of the magnetization vector.
