Abstract
Measurements of magnetization and susceptibility were carried out in the temperature range from 4.2 to 300 K for amorphous Co 100- x R x (R = Sm, Nd, Pr; 50 ⩽ x ⩽ 70) alloys prepared by a rapid quenching technique. The magnetic properties of these amorphous alloys are discussed based on a local moment model. It is concluded that the rare earth R in the amorphous alloys behaves as trivalent positive ions, and that the magnitude of effective magnetic moment inherent in Co ion decreases with an increase of x and almost vanishes around x = 60.
