Abstract

We theoretically and numerically investigate magnetic domain wall dynamics in a nanowire of easy-cone magnet. The easy-cone domain wall exhibits several distinguishing dynamic features in comparison to the easy-axis domain wall. The features of easy-cone domain wall are related to the generation of additional chiral spin textures due to the domain wall precession, which is common for various driving sources such as magnetic fields and spin-transfer torques. The unique easy-cone domain wall dynamics could enrich magnetic domain wall study and find use in device applications based on easy-cone domain walls.
