      abstract     = {The diversity of three-dimensional magnetic states in a
                      FeGe nanocylinder is studied using micromagnetic simulations
                      and off-axis electron holography in the transmission
                      electron microscope. In particular, we report the
                      observation of a dipole string—a spin texture composed of
                      two coupled Bloch points—which becomes stable under
                      geometrical confinement. Quantitative agreement is obtained
                      between experimental and theoretical phase shift images by
                      taking into account the presence of a damaged layer on the
                      surface of the nanocylinder. The theoretical model is based
                      on the assumption that the damaged surface layer, which
                      results from focused ion beam milling during sample
                      preparation, has similar magnetic properties to those of an
                      amorphous FeGe alloy. The results highlight the importance
                      of considering the magnetic properties of the surface layers
                      of such nanoscale samples, which influence their magnetic
                      states},
