      abstract     = {Rare earth doping is the key strategy to increase the Curie
                      temperature (T-C) of the ferromagnetic semiconductor EuO.
                      The interplay between doping and charge carrier density (n),
                      and the limit of the T-C increase, however, are yet to be
                      understood. We report measurements of n and T-C of Gd-doped
                      EuO over a wide range of doping levels. The results show a
                      direct correlation between n and T-C, with both exhibiting a
                      maximum at high doping. On average, less than $35\%$ of the
                      dopants act as donors, raising the question about the limit
                      to increasing T-C.},
