Magnetic skyrmions were thought to be stabilised only in inversion-symmetry breaking structures, but skyrmion lattices were recently discovered in inversion symmetric Gd-based compounds, spurring questions of the stabilisation mechanism. A natural consequence of a recent theoretical proposal, a coupling between itinerant electrons and localised magnetic moments, is that the skyrmions are amenable to detection using even non-magnetic probes such as spectroscopic-imaging scanning tunnelling… Expand

Skyrmion lattice with a giant topological Hall effect in a frustrated triangular-lattice magnet
A giant topological Hall response is observed, indicating a field-induced skyrmion phase, which is further corroborated by the observation of in-plane spin modulation probed by resonant x-ray scattering, and may lead to further discoveries of emergent electrodynamics in magnetically frustrated centrosymmetric materials.
