Query: Spin relaxation in disordered graphene: Interplay between puddles and
  defect-induced magnetism   We study the spin relaxation in graphene due to magnetic moments induced by
defects. We propose and employ in our studies a microscopic model that
describes magnetic impurity scattering processes mediated by charge puddles.
This model incorporates the spin texture related to the defect-induced state.
We calibrate our model parameters using experimentally-inferred values. The
results we obtain for the spin relaxation times are in very good agreement with
experimental findings. Our study leads to a comprehensive explanation for the
short spin relaxation times reported in the experimental literature. We also
propose a new interpretation for the puzzling experimental observation of
enhanced spin relaxation times in hydrogenated graphene samples in terms of a
combined effect due to disorder configurations that lead to an increased
coupling to the magnetic moments and the tunability of the defect-induced
$\pi$-like magnetism in graphene.
