      abstract     = {We present a detailed analysis of the electronic properties
                      of graphene/Eu/Ni(111). By using angle and spin-resolved
                      photoemission spectroscopy and ab initio calculations, we
                      show that the Eu-intercalation of graphene/Ni(111) restores
                      the nearly freestanding dispersion of the ππ∗ Dirac
                      cones at the K point with an additional lifting of the spin
                      degeneracy due to the mixing of graphene and Eu states. The
                      interaction with the magnetic substrate results in a large
                      spin-dependent gap in the Dirac cones with a topological
                      nature characterized by a large Berry curvature, and a
                      spin-polarized van Hove singularity, whose closeness to the
                      Fermi level gives rise to a polaronic band.},
