Micromagnetic simulation of current-driven domain wall propagation
We develop a method to model the interaction of currents and domain walls in a standard micromagnetic simulator. The interaction of spin-polarized currents and localized magnetic moments can be described by a current-induced effective field, which superposes to other components of the effective magnetic field. Using our method, we examine domain wall propagation in ideal, rough-surfaced and notched domain walls.
