Theoretical study of current-induced domain wall motion in magnetic nanotubes with azimuthal domains

We report a theoretical overview of the magnetic domain wall behavior under an electric current in infinitely long nanotubes with azimuthal magnetization, combining one-dimensional analytic model and micromagnetic simulations. highlight effects that, besides spin-transfer torques already largely understood flat strips, arise specifically tubular geometry: \OE{}rsted field curvature-induced anisotropy resulting both from exchange interaction material growth. Depending on geometry tube strength anisotropy, Bloch or N\'eel walls at rest, two regimes motion dominated by either field. determine Walker breakdown all cases, most suitable parameters to achieve high speed.
