Abstract:
The strengths of the Gd-Gd, Gd-Fe and Fe-Fe exchange couplings have been estimated from
ordering temperatures for the amorphous Gd-T (T = Cu, Al and Fe) systems. The obtained Gd-Gd and Gd-
Fe exchange interactions always increase with increasing Gd-concentration. These results are associated to
the 5d-electron density. The Fe-Fe coupling, however, was discussed in terms of the negative interactions
between the Fe-Fe pairs with the closest inter-atomic spacing. ?? 1998 Elsevier Science B.V. All rights
