      abstract     = {When electrons are driven through unconventional magnetic
                      structures, such as skyrmions, they experience emergent
                      electromagnetic fields that originate several Hall effects.
                      Independently, ground-state emergent magnetic fields can
                      also lead to orbital magnetism, even without the
                      spin–orbit interaction. The close parallel between the
                      geometric theories of the Hall effects and of the orbital
                      magnetization raises the question: does a skyrmion display
                      topological orbital magnetism? Here we first address the
                      smallest systems with nonvanishing emergent magnetic field,
                      trimers, characterizing the orbital magnetic properties from
                      first-principles. Armed with this understanding, we study
                      the orbital magnetism of skyrmions and demonstrate that the
                      contribution driven by the emergent magnetic field is
                      topological. This means that the topological contribution to
                      the orbital moment does not change under continuous
                      deformations of the magnetic structure. Furthermore, we use
                      it to propose a new experimental protocol for the
                      identification of topological magnetic structures, by soft
                      X-ray spectroscopy.},
