  • Dynamic Kerr microscopy enables the tracking of the two-step melting of a magnetic skyrmion lattice from a two-dimensional solid through an intermediate hexatic regime to an isotropic liquid and provides direct insights in the occurrence and dynamics of lattice dislocations, the defects that mediate melting.

  • Magnetic skyrmions are chiral spin structures that can form two-dimensional lattices. Here, the authors show how lattice domains grow under the influence of pinning effects in a non-flat energy landscape and that magnetic field oscillations help to stabilize order.

  • Magnetic skyrmions, due to their strongly nonlinearity and multiscale dynamics, are promising for implementing reservoir computing. Here, the authors experimentally demonstrate skyrmion-based spatially multiplexed reservoir computing able to perform Boolean Logic operations, using thermal and current driven dynamics of spin structures.

  • Efforts to understand skyrmion behaviour often overlook the interaction potentials but these are key to improve predictive modelling. Here, the authors use an Iterative Boltzmann Inversion technique to construct potentials for skyrmion-skyrmion and skyrmion-boundary interactions from a single experimental measurement, finding the two interactions are exponentially repulsive.
