      abstract     = {The fabrication of bit-patterned media (BPM) is crucial for
                      new types of hard disk drives. The development of methods
                      for the production of BPM is progressing rapidly.
                      Conventional lithography reaches the limit regarding lateral
                      resolution, and new routes are needed. In this study, we
                      mainly focus on the dependence of the size and shape of
                      magnetic nanodots on the Ar+-ion etching duration, using
                      silica dots as masks. Two-dimensional (2D) arrays of
                      magnetic nanostructures are created using silica-filled
                      diblock-copolymer micelles as templates. After the
                      self-assembly of the micelles into 2D hexagonal arrays, the
                      polymer shell is removed, and the SiO2 cores are utilized to
                      transform the morphology into a (Co/Pt)2-multilayer via ion
                      etching under normal incidence. The number of preparation
                      steps is kept as low as possible to simplify the formation
                      of the nanostructure arrays. High-resolution in situ
                      grazing-incidence small-angle X-ray scattering (GISAXS)
                      investigations are performed during the Ar+-ion etching to
                      monitor and control the fabrication process. The in situ
                      investigation provides information on how the etching
                      conditions can be improved for further ex situ experiments.
                      The GISAXS patterns are compared with simulations. We
                      observe that the dots change in shape from cylindrical to
                      conical during the etching process. The magnetic behavior is
                      studied by utilizing the magneto-optic Kerr effect. The
                      Co/Pt dots exhibit different magnetic behaviors depending on
                      their size, interparticle distance, and etching time. They
                      show ferromagnetism with an easy axis of magnetization
                      perpendicular to the film. A systematic dependence of the
                      coercivity on the dot size is observed.},
