      abstract     = {In this theoretical investigation we demonstrate that the
                      adsorption of spatially extended two-dimensional (2D) π
                      systems such as graphene and hexagonal boron nitride on the
                      ferromagnetic fcc Co(111) surface leads to a specific
                      behavior of the in-plane and interlayer Co-Co magnetic
                      exchange interactions. More specifically, for both systems
                      the magnetic exchange coupling within the first Co layer is
                      enhanced, while the one between the first and the second Co
                      layer is not modified, in contrast to the magnetic
                      interlayer softening induced by organic molecules.
                      Importantly, the in-plane magnetic hardening effect is
                      mainly due to the hybridization between the pz states of the
                      2D π system and the d states of the Co surface.},
