Calculations of skyrmions in antiferromagnets (AFMs) are presented, and their properties compared with skyrmions in corresponding ferromagnets (FMs). The rates of skyrmion collapse and escape through the boundary of a track, as well as the binding to and collapse at a non-magnetic impurity is calculated as a function of applied magnetic field. In the absence of an applied magnetic field, the activation energy for skyrmion annihilation is the same. The pre-exponential factor in the Arrhenius…
