Abstract
A systematic study was made of the magnetic properties of the amorphous alloys: , , and . Results indicate that GdCo, GdNi, and GdCoNi alloys are collinear ferrimagnets involving electron transfer from Gd to the elements. However, GdFe, GdFeNi, and GdFeCo alloys containing less than 30% Co are sperimagnetic due to antiferromagnetic interactions in the Fe subnetwork. Mean-field exchange energies are calculated and used to explain the results. A Slater-Pauling-type curve is constructed, and the dependence of properties on the average number of transition-metal electrons is discussed.
