Our results remain the same essentially even on samples homogenized at 1100 K (for one week) and quenched to 300 K. It is claimed (Ref.) that this family of compounds cannot be considered "line compounds" and that there could be a small solubility range. In view of this, it is possible that a marginal off stoichiometry may result in local environmental effects, thereby resulting in additional transitions seen in these articles. We may also mention that the sharpness of the transition at 69 K is not attributable to first-order character, as we did not find any hysteresis in the data for warming and cooling cycles.

    • The paramagnetic behavior is by itself interesting and not understandable. In zero field, the temperature coefficient of resistivity is negative over a wide temperature range above TN, resulting in a broad minimum in ρ (T) around 200 K. The magnitude of MR is large even at temperatures far away from TN, say about -12% for H=100 kOe at 110 K. At 200 K, the corresponding value is found to be about -2%. Similar behavior has been reported by us in some other Gd and Tb compounds. See, for instance, 10.1209/epl/i1998-00149-4;
