Abstract :
Magnetic properties of (GdxY(1-x)n+1Co3n+5B2n compounds with n=1, 2, 3 and n→∞ were studied in the temperature range 4-800 K and external field up to 7 T. The compounds with x⩾0.2 are ferrimagnetically ordered. The cobalt and gadolinium magnetizations at 4 K, compensate at x=0.43 (n=1), x=0.31 (n=2) and x=0.26 (n=3). Within a given series, the mean cobalt moments determined at 4 K are strongly dependent on the composition, while the effective cobalt moments deduced from the Curie constants in the paramagnetic phase are only a little composition dependent. The magnetic behaviour of cobalt in the studied system is analyzed
