Illustration of a h2h VDW in MNTs. Counterclockwise (p = 0) and clockwise (p =pi) are the possible vortex chiralities. The magnetization components can be expressed through the angles theta and p, and the main properties of the DW are cast by the position in the z axis, the wall width w, and the DW magnetization angle p.
