Abstract = {The rare-earth pyrosilicate family of compounds (RE2Si2O7) hosts a
   variety of polymorphs, some with honeycomb-like geometries of the
   rare-earth sublattices, and the magnetism has yet to be deeply explored
   in many of the cases. Here we report on the ground state properties of
   C-Er2Si2O7. C-Er2Si2O7 crystallizes in the C2/m space group and the Er3+
   atoms form a distorted honeycomb lattice in the a-b plane. We have
   utilized specific heat, DC susceptibility, and neutron diffraction
   measurements to characterize C-Er2Si2O7. Our specific heat and DC
   susceptibility measurements show signatures of antiferromagnetic
   ordering at 2.3 K. Neutron powder diffraction confirms this transition
   temperature and the relative intensities of the magnetic Bragg peaks are
   consistent with a collinear Neel state in the magnetic space group
   C2'/m, with ordered moment of 6.61 mu(B) canted 13 degrees away from the
   c-axis toward the a-axis. These results are discussed in relation to the
   isostructural quantum dimer magnet compound Yb2Si2O7.},
