      abstract     = {Whereas theoretical investigations have revealed the
                      significant influence of magnetic surface and edge states on
                      Skyrmonic spin texture in chiral magnets, experimental
                      studies of such chiral states remain elusive. Here, we study
                      chiral edge states in an FeGe nanostripe experimentally
                      using off-axis electron holography. Our results reveal the
                      magnetic-field-driven formation of chiral edge states and
                      their penetration lengths at 95 and 240 K. We determine
                      values of saturation magnetization MS by analyzing the
                      projected in-plane magnetization distributions of helices
                      and Skyrmions. Values of MS inferred for Skyrmions are lower
                      by a few percent than those for helices. We attribute this
                      difference to the presence of chiral surface states, which
                      are predicted theoretically in a three-dimensional Skyrmion
                      model. Our experiments provide direct quantitative
                      measurements of magnetic chiral boundary states and
                      highlight the applicability of state-of-the-art electron
                      holography for the study of complex spin textures in
                      nanostructures.},
