Chiral breakdown engineered by mesoscale Dzyaloshinskii-Moriya interaction in biaxial magnetic nanotubes

Abstract

Curvilinear geometries in magnetic nanostructures provide a unique platform for exploring the interplay among symmetry, topology, and curvature in magnetization dynamics. In this paper, we analytically study the static and dynamic properties of magnetic domain walls in biaxial magnetic nanotubes with intrinsic Dzyaloshinskii-Moriya interaction of different symmetries. We show that geometry-driven local and nonlocal interactions govern domain profiles and dynamics, enabling precise control over wall propagation and Walker breakdown field. Furthermore, the combination of bulk-Type Dzyaloshinskii-Moriya interaction and curvature leads to chirality symmetry breaking and chiral breakdown in magnetic domain wall motion. These findings offer a framework for tailoring domain wall textures in cylindrical nanotubes, unlocking functionalities for advanced applications in curvilinear magnonics and data storage technologies.
