      abstract     = {In this thesis magnetic domain patterns of ferromagnetic
                      alloys are studied using resonant magnetic scattering (RMS).
                      For this purpose synchrotron radiation in the soft X-ray
                      range and laser-based extreme ultraviolet (XUV) light from a
                      laboratory light source are employed. The synchrotron
                      measurements give detailed information about the properties
                      of magnetic domains with nanometer precision and element
                      selectivity. These specialties allow investigations of
                      domain patterns of complex layered systems, including
                      FePd/CoPd bilayers or CoPd/Pd/NiFe trilayers. Time-resolved
                      experiments with visible laser radiation are conducted to
                      examine the laserinduced demagnetization of FePd/CoPd
                      bilayers, pointing out the influence of intense laser pulses
                      on the magnetic coupling of the two layers. This technique
                      is capable of tracing the temporal evolution of the
                      magnetization, nevertheless it cannot image nanometer-sized
                      magnetic domains due to the limited spatial resolution.
                      Consequently, a new approach is necessary to resolve domain
                      patterns and ultrafast magnetization dynamics at the same
                      time. This aim motivates the most important question
                      addressed in this thesis: whether a tabletop XUV light
                      source based on high-order harmonic generation (HHG) can be
                      used for RMS experiments on magnetic domain patterns. In
                      this context it is further shown, how intense laser exposure
                      causes permanent and reversible modifcations of the magnetic
                      nanostructure and the sample morphology. Finally, coherence
                      properties of the generated XUV radiation are examined,
                      using nonmagnetic scattering at grains and knife-edge
                      diffraction. The results obtained reveal the advantages and
                      limitations of HHG sources for applications which demand a
                      high light coherence.},
