Abstract: | The magnetic properties of several amorphous rare-earth nickel alloys close to 30 at% Ni have been studied in the temperature range 4.2–300 K. The Curie temperatures range from 2 K in Pr69Ni31. Alloys in which the rare-earth component has an orbital moment show large intrinsic coercive forces below Tc. These coercive forces vary considerably with temperature, the temperature dependence of the alloys Dy69Ni31 and Tb69Ni31 is satisfactorily described by means of an exponential law of the form Hc(T) = Hc(0) exp(-αT). |
