(a) Simulated configuration of a vortex-like DW formed in a magnetic nanotube and the definition of its chirality by combining vorticity and field direction. (b) The unrolled tube with the DW. The red line is the plot of the radial component averaged over each cross-section. (c) For comparison, a transverse DW in a flat strip.
