Abstract The magnetization curves at 1.5K and Curie temperature of amorphow (Fe_100-xB_x)₈₈ Nd_12±ε alloys were measured. Their spontaneous magnetizations is explained by a noncollinear structure. The average magnetic moment μ_Fe per Fe atom decreases monotonically with increasing x, and becomes more rapid when x > 24. The B content dependence of Curie temperature shows a mazimum at x = 15. At x< 15, the increase of T_c with x may be attributed to the indirect exchange interactions between Fe-Fe atoms.
