      abstract     = {Magnetic skyrmions are localized, stable topological
                      magnetic textures that can move and interact with each other
                      like ordinary particles when an external stimulus is
                      applied. The efficient control of the motion of spin
                      textures using spin-polarized currents opened an opportunity
                      for skyrmionic devices such as racetrack memory and
                      neuromorphic or reservoir computing. The coexistence of
                      skyrmions with high topological charge in the same system
                      promises further possibilities for efficient technological
                      applications. In this work, we directly observe dipolar
                      skyrmions and antiskyrmions with arbitrary topological
                      charge in Co/Ni multilayers at room temperature. We explore
                      the dipolar-stabilized spin objects with topological charges
                      of up to 10 and characterize their nucleation process, their
                      energy dependence on the topological charge and the effect
                      of the material parameters on their stability. Furthermore,
                      our micromagnetic simulations demonstrate
                      spin-transfer-induced motion of these spin objects, which is
                      important for their potential device application.},
