      abstract     = {Magnetic skyrmions are complex swirling spin structures
                      that are of interest for applications in energy-efficient
                      memories and logic technologies. Multilayers of heavy metals
                      and ferromagnets have been shown to host magnetic skyrmions
                      at room temperature. Lorentz transmission electron
                      microscopy is often used to study magnetic domain structures
                      in multilayer samples using mainly Fresnel defocus imaging.
                      Here, off-axis electron holography is used to obtain
                      in-focus electron optical phase images of Néel-type domains
                      and skyrmions in an Ir/Fe/Co/Pt multilayer sample. The
                      preparation of the sample, reconstruction of the holograms
                      and influence of sample tilt angle on the signal-to-noise
                      ratio in the phase images are discussed. A good agreement is
                      found between images of individual skyrmions that are
                      stabilized using an external magnetic field and simulated
                      images based on theoretical models of Néel-type skyrmions.},
