a, In a Bloch-type skyrmion, the spins rotate in the tangential
planes—that is, perpendicular to the radial directions—when moving from
the core to the periphery. b, In a Néel-type skyrmion, the spins
rotate in the radial planes from the core to the periphery. The
cross-section of the vortex is also depicted in both cases. |
