The GdCo4-xNixAl system forms solid solutions in all the composition range.
The compounds are ferrimagnetically ordered. The mean cobalt moments at 4.
2 K, decrease with increasing nickel content. The effective cobalt and nick
el moments are not dependent on composition. The effect of exchange interac
tions on cobalt moments is analyzed. (C) 1999 Elsevier Science B.V. All rig
