Query: Magnetic structure of the noncentrosymmetric heavy-fermion
  superconductor CePt3Si   We have determined the magnetic structure of the noncentrosymmetric
heavy-fermion superconductor CePt3Si using elastic polarized neutron scattering
with field-projected (longitudinal) XYZ polarization analysis. We find that the
magnetic moment has components both in the tetragonal basal plane and along the
tetragonal four-fold axis. Such a magnetic structure is not symmetry-allowed if
the magnetic phase transition is second order, and may imply that CePt3Si has
lower symmetry in the superconducting state than originally thought.
