Magnetic properties of melt-spun Fel_xNdx amorphous alloys are examined. Magnetically homogeneous alloys were obtained in the range of 0.15 x 0.60. The Curie point is lowered by decrease of x down to room temperature. The internal field at 57Fe nuclei is almost constant, 300 kOe, at 77 K, suggesting that the Fe moment is nearly constant in this range. The coercive field at 4.2 K is as ‘small as 1 kOe for x = 0.2 but increases rather abruptly for larger x, up to more than 50 kOe for x 0;4. Large random uniaxial anisotropy of Nd is supposed to be the cause of such a high coercivity.
