Query: Mechanical and liquid phase exfoliation of cylindrite: a natural van der
  Waals superlattice with intrinsic magnetic interactions   We report the isolation of thin flakes of cylindrite, a naturally occurring
van der Waals superlattice, by means of mechanical and liquid phase
exfoliation. We find that this material is a heavily doped p-type semiconductor
with a narrow gap (<0.85 eV) with intrinsic magnetic interactions that are
preserved even in the exfoliated nanosheets. Due to its environmental stability
and high electrical conductivity, cylindrite can be an interesting alternative
to the existing two-dimensional magnetic materials.
