Abstract

Hedgehogs, Whirls, and Zippers Topologically ordered materials at certain ranges of temperature and magnetic field can form a regular lattice of magnetic whirls called skyrmions. Milde et al. (p. 1076 ) studied the destruction of a skyrmion lattice with varying magnetic fields by imaging the surface magnetic structure. Magnetic force microscopy revealed a pairwise merging of skyrmions on the surface. Furthermore, in the bulk, a hedgehog-like spin structure with the properties of the elusive magnetic monopole was needed to "zip" together the corresponding skyrmion lines.
