Exact soliton solutions in anisotropic ferromagnetic wires with Dzyaloshinskii-Moriya interaction

doi:10.1088/1674-1056/abca26

Abstract We theoretically investigate the exact soliton solutions of anisotropic ferromagnetic wires with Dzyaloshinskii-Moriya interaction. For example, we give the bright and black soliton solutions. From these results we find that the Dzyaloshinskii-Moriya interaction affects the existence region of soliton, spin-wave transport, and soliton dynamic properties. As the Dzyaloshinskii-Moriya interaction grows, the soliton width is widened, which provides a way to control the soliton dynamics.

Keywords: bright soliton black soliton Dzyaloshinskii-Moriya interaction
