Abstract
The spin-polarized electronic structure of an amorphous alloy was calculated in a Gd33Fe67 alloy for the first time, a result long awaited because it allows us to clarify the magnetic and magneto-optical properties. The calculated density of states of the Fe and Gd d-state show roughly a single peak structure. The resultant magnetic moment of Fe is 2.0μB, and shows good agreement with experimental value of 1.9μB. The contribution of each constituent atom to the Kerr effect is well manifested on the basis of the obtained electronic structure.
