Domain wall dynamics in easy-cone magnets

Abstract

We theoretically and numerically investigate magnetic domain wall dynamics in a nanowire of an easy-cone magnet. The easy-cone domain wall exhibits several distinguishing dynamic features in comparison to the easy-axis domain wall. They are related to the generation of additional chiral spin textures due to the domain wall precession, which occurs commonly for various driving sources such as magnetic fields and spin-transfer torque. We envision that the unique easy-cone domain wall dynamics can enrich the study of magnetic domain walls both for fundamental interest and for device applications.
