Abstract Magnetization, Curie temperature and crystallization temperature measurements for amorphous (Fe1-xNdx)100-yBy alloys with y=6, 18.5 and 25 have been made. Spontaneous magnetization shows a monotonic decrease with x, and the noncollinear spin structures have been proposed to explain the observed results. The composition dependence of Curie temperature is explained by the average molecular-field model. The substitution of small Nd for Fe is found to have a strong enhancement of the thermal stability in amorphous Fe-Nd-B alloys.
