Abstract
Magnetic measurements performed on (GdxY1-x)(n+1)Co3n+5B2n compounds w ith n=1, 2 and 3 show a great dependence of cobalt moments, determined at 4 K, on the exchange interactions. The effective cobalt moments, f or a given series, are only slightly modified. The magnetic behaviour of cobalt is analyzed in the spin fluctuation model. A gradual quenchi ng of spin fluctuations is evidenced when the exchange fields acting o n cobalt increase.
