Observation of a transverse magnetization in the ordered phases of the   pyrochlore magnet Gd2Ti2O7
  We have performed a detailed transverse magnetization study of the pyrochlore antiferromagnet Gd2Ti2O7. A transverse magnetization of about 10^{-3}M_{sat} is observed in the low-temperature ordered phases. These measurements result in the refinement of the Gd2Ti2O7 phase diagrams. Observation of a transverse magnetization indicates loss of the cubic symmetry in some of the magnetic phases and provides new information for a better understanding of the complicated magnetic ordering of Gd2Ti2O7.
