摘要：

The field dependence (up to 35 T) of the magnetization at 4.2 K of several compounds of the type R1-xYxCo12B6 has been studied. The magnetic isotherms were analysed with a mean-field model. Values for the magnetic-coupling constant J(RCo) between the moments of the rare earth (R) and Co in the Hamiltonian H = SIGMA(RCo)2J(RCo)S(R)S(Co) were determined and compared with those obtained earlier for RCo4B and R2Co14B compounds.
