      abstract     = {Magnetic chiral skyrmions are vortex like spin structures
                      that appear as stable or meta-stable states in magnetic
                      materials due to the interplay between the symmetric and
                      antisymmetric exchange interactions, applied magnetic field
                      and/or uniaxial anisotropy. Their small size and internal
                      stability make them prospective objects for data storage but
                      for this, the controlled switching between skyrmion states
                      of opposite polarity and topological charge is essential.
                      Here we present a study of magnetic skyrmion switching by an
                      applied magnetic field pulse based on a discrete model of
                      classical spins and atomistic spin dynamics. We found a
                      finite range of coupling parameters corresponding to the
                      coexistence of two degenerate isolated skyrmions
                      characterized by mutually inverted spin structures with
                      opposite polarity and topological charge. We demonstrate how
                      for a wide range of material parameters a short inclined
                      magnetic field pulse can initiate the reliable switching
                      between these states at GHz rates. Detailed analysis of the
                      switching mechanism revealed the complex path of the system
                      accompanied with the excitation of a chiral-achiral meron
                      pair and the formation of an achiral skyrmion.},
