      abstract     = {From macroscopic heavy-duty permanent magnets to
                      nanodevices, the precise control of the magnetic properties
                      in rare-earth metals is crucial for many applications used
                      in our daily life. Therefore, a detailed understanding and
                      manipulation of the 4f-metals’ magnetic properties are key
                      to further boosting the functionalization and efficiency of
                      future applications. We present a proof-of-concept approach
                      consisting of a dysprosium-iridium surface alloy in which
                      graphene adsorption allows us to tailor its magnetic
                      properties. By adsorbing graphene onto a long-range ordered
                      two-dimensional dysprosium-iridium surface alloy, the
                      magnetic 4f-metal atoms are selectively lifted from the
                      surface alloy. This selective skyhook effect introduces a
                      giant magnetic anisotropy in dysprosium atoms as a result of
                      manipulating its geometrical structure within the surface
                      alloy. Introducing and proving this concept by our combined
                      theoretical and experimental approach provides an easy and
                      unambiguous understanding of its underlying mechanism. Our
                      study sets the ground for an alternative path on how to
                      modify the crystal field around 4f-atoms and therefore their
                      magnetic anisotropies.},
