10.1103/PhysRevB. 102.144420], Cabrera-Baez et al., present a study of the effects of Cd
substitution for Zn in the ferromagnetic compound GdFe 2 Zn 20. As part of this paper they
claim that for GdFe 2 Zn 18.6 Cd 1.4 the effective moment of Gd is reduced by 25%, and the
saturated moment of Gd is reduced by over 40%. We regrew representative members of the
GdFe 2 Zn 20− x Cd x series and did not find any such reductions. In addition, we measured …

As part of this paper they claim that for the effective moment of Gd is reduced by 25%, and the saturated moment of Gd is reduced by over 40%. We regrew representative members of the series and did not find any such reductions. In addition, we measured several crystals from the growth batch that was used by Cabrera-Baez et al. and did not see such reductions. Although there is a modest increase in with Cd substitution, there is no significant change in the Gd effective moment or the saturated moment associated with the low-temperature ferromagnetic state.
