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 B\"{a}cklund transformation technique. It is pointed out that the traveling soliton carries the magnon density and a magnetic solition transport may be realized.<br />Comment: 10 pages, 3 figures
