Abstract

Magnetic properties of melt-spun Fe//1//31 //xNd//x amorphous alloys are examined. Magnetically homogeneous alloys were obtained in the range of 0. 15 less than equivalent to x less than equivalent to 0. 60. The Curie point is lowered by decrease of x down to room temperture. The internal field at **5**7Fe nuclei is almost constant, 30 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 equals 0. 2 but increases rather abruptly for larger x, up to more than 50 kOe for x greater than equivalent to 0. 4. Large random uniaxial anisotropy of Nd is supposed to be the cause of such a high coercivity.
