Constructing coarse-grained skyrmion potentials from experimental data with Iterative Boltzmann Inversion
Abstract
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.
