We calculate the spin-dependent zero-bias conductance Gσσ′ in armchair graphene nanoribbons with hydrogen adsorbates employing a DFT-based ab initio transport formalism including spin-orbit interaction. We find that the spin-flip conductance Gσσ¯ can reach the same order of magnitude as the spin-conserving one Gσσ, due to exchange-mediated spin scattering. In contrast, the genuine spin-orbit interaction appears to play a secondary role, only.
