Cobalt-induced moments in ternary gadolinium--yttrium compounds. [Gd/sub x/Y/sub 1-x/Co/sub 2/; 4. 2 to 1300/sup 0/K]
Results of magnetic measurements on (Gd/sub x/Y/sub 1-x/)CO/sub 2/ compounds between 4.2 and 1300/sup 0/K are presented. The experimental data are analyzed assuming that the cobalt atoms present a paramagnetic moment or an exchange-enhanced paramagnetism. Both models showed that the cobalt-ordered moments are linearly dependent on the exchange field acting on these atoms (H/sub ex/M/sup 0//sub Co/ approximately equal to 3.10/sup 6/ Gs/..mu../sub B/), being essentially induced by the magnetic interactions. The experimental data seem to be in agreement with the presence of the cobalt paramagnetic contribution. No first-order transition in these systems is observed. 7 figures, 4 tables. (auth)
