摘要：

Magnetization measurements have been carried out for Y1-xNdxCo3 compounds with 0 less-than-or-equal-to x less-than-or-equal-to 1 in ultrahigh magnetic fields up to 110 T. The compound exhibits two metamagnetic transitions of the Co sublattice to a higher moment state. Both transition fields decrease with increasing Nd concentration due to the exchange field from the Nd sublattice acting on the Co sublattice. From the concentration dependence of the transition fields the average exchange parameter between Nd and Co is estimated to be J(NdCo) = 2.0 x 10(-22) J. The spontaneous Co moment and the Curie temperature also exhibit an anomalous increase with Nd concentration, which originates from the transitions.
