      abstract     = {A key feature of extreme ultraviolet (XUV) radiation from
                      free-electron lasers (FELs) is its spatial and temporal
                      coherence. We measured the spatio-temporal coherence
                      properties of monochromatized FEL pulses at 13.5 nm using a
                      Michelson interferometer. A temporal coherence time of
                      (59±8) fs has been determined which is in good agreement
                      with the spectral bandwidth given by the monochromator.
                      Moreover, the spatial coherence in vertical direction
                      amounts to about $15\%$ of the beam diameter and about
                      $12\%$ in horizontal direction. The feasibility of measuring
                      spatio-temporal coherence properties of XUV FEL radiation
                      using interferometric techniques advances machine operation
                      and experimental studies significantly.},
