Amorphous films with composition Gd/sub 18/Fe/sub 82-x/Ni/sub x/ where x varies from 12 to 68 have been prepared by evaporation. By comparing Gd-Fe-Ni with binary Gd-Fe, Gd-Au and Y-Fe amorphous alloys using both magnetization and spontaneous Hall data we analyze Gd-Fe-Ni first as a two sublattice system of Gd and Fe-Ni followed by separate consideration of the Fe and Ni. Based on a small decrease associated with the Fe magnetization it is calculated that the magnetization of nickel is strongly dependent on the composition, showing a decrease in moment with increasing nickel content, diminishing to almost zero at 66 percent Ni. For all compositions the Hall coefficient of Ni is found to be negative. Gd also has a negative Hall coefficient while Fe is positive.
