Magnetic properties of (Gd{sub x}Y{sub 1{minus}x}){sub n+1}Co{sub 3n+5}B{sub 2n} compounds with n = 1, 2, 3 and n {r_arrow} {infinity} were studied in the temperature range 4--800 K and external field up to 7 T. The compounds with x {ge} 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 4K are strongly dependent on the composition, while the effective cobalt moments decoded from the Curie constants in the paramagnetic phase are only a little composition dependent. The magnetic behavior of cobalt in the studied system is analyzed.
