Current-driven dynamics of chiral ferromagnetic domain walls
2013
Controlling the direction of propagation of domain walls in magnetic nanowires is essential for their use in proposed device applications. It is now shown that Dzyaloshinskii–Moriya interactions determine the chirality of domain walls in metallic ferromagnets placed between a heavy metal and an oxide, which in turn means the direction of propagation can be determined by choosing suitable material properties.
