Iron-rich pseudobinary alloys with the ThMn12 structure obtained by melt spinning : Gd(FenAl12-n), n = 6, 8, 10
Résumé
The compounds GdFe8Al4 and GdFe10Al2 with the ThMn12 structure were obtained by melt spinning and annealing at 450 °C. They are ferri-magnetic with net moments at room temperature of 6.1 and 10.6 μB formula unit−1 respectively. Iron hyperfine fields range from 19–27 T in GdFe10Al2. There is no non-magnetic iron site. The extrapolated Curie temperature for “GdFe12” is 600 K.
