This study of amorphous Gd-Mn, Y-Mn and their ternary alloys with Co prepared as films by co-evaporation indicates that, (a) the Mn moment is compositionally dependent going from ?2μB to 0.5μB per Mn with increased Mn concentration in the alloy, (b) Gd-Mn and Gd- (CoMn) order with antiparallel Gd and Mn moments or (CoMn) moments while Y-Mn samples remain paramagnetic, (c) Curie temperatures are relatively constant with composition which we have interpreted in terms of the Mn-Mn exchange interaction, and (d) the spontaneous Hall effect for Mn as given by ρH/ρ (Hall resistivity/sample resistivity) is about -0.01 per μB of Mn which is opposite in sign to Fe or Co.
