Abstract:

We show the existence of an isolated soliton excitation over the topological ground-state configuration in chiral helimagnet with the Dzyaloshinskii-Moryia exchange and the strong easy-plane anisotropy. The magnetic field perpendicular to the helical axis stabilizes the kink crystal state which plays a role of ``topological protectorate{''} for the traveling soliton with a definite handedness. To find new soliton solution, we use the Backlund transformation technique. It is pointed out that the traveling soliton carries the magnon density and a magnetic soliton transport may be realized.
