Comparison Between the Magnetic Properties of Crystalline and Amorphous Rare Earth Transition Metal Alloys
The atomic arrangement of the rare earth (R)-transition metal (M) alloys in both crystalline and amorphous states may be described as a packing of spheres of different radii. Their magnetic properties result mainly from the large difference in electronegativity between the two constituents (1). However the loss of rotational and translational symmetries in the amorphous state may influence strongly some of these properties.
