Dispersive Stiffness of Dzyaloshinskii Domain Walls
Dispersive Stiffness of Dzyaloshinskii Domain Walls
It is well documented that subjecting perpendicular magnetic films which exhibit the interfacial Dzyaloshinskii-Moriya interaction (DMI) to an in-plane magnetic field results in a domain wall (DW) energy, $\sigma$, that is highly anisotropic with respect to the orientation of the DW in the film plane, $\Theta$. We demonstrate that this …
