Topological dynamical soliton in a two-dimensional uniaxial ferromagnet

Using the Landau–Lifshits equations without damping we study the bound state of a large number of magnons with a nonzero angular momentum. It is shown that this dynamical soliton is associated with topological singularity. The characterisics of this soliton are obtained on a computer in a wide range of frequencies of precession of the magnetization vector.
