An international team of researchers (Germany, China) experimentally probed the dramatic influence of confinement on diffusion and study the skyrmion diffusion in confined geometries varying both the symmetry of the elements and the number of skyrmions within the element, studying the evolution from a sparse population to a fully lattice‐like situation and skyrmion population. In the triangular geometry, they found that the dynamics varies drastically for numbers of skyrmions that can form a regular order, thus being commensurate with the geometry, as compared to numbers of skyrmions that are incommensurate with the geometry. The findings confirm experimentally a novel commensurability effect of thermal dynamics of skyrmions in confined geometries and provide a potential method to control diffusive dynamics by tuning the number of skyrmions and the element geometry. The study will be useful as a first necessary step toward the construction of basic computational components in Brownian computing…read more. Open Access TECHNICAL ARTICLE
