On the Travelling Wave Solution for the Current-Driven Steady Domain Wall Motion in Magnetic Nanostrips under the Influence of Rashba Field

Figure 4

Current-driven DW velocities in the steady dynamic regime with and without the inclusion of the dry-friction dissipation function in the mathematical model ( and , resp.). The limit of Walker has not been considered in this figure in order to better emphasize the nonlinear behavior of the DW velocity influenced by internal disorder, , with respect to the case . Walker breakdown conditions, indeed, are not influenced by .
