摘要：

The effect of substitution of cerium by yttrium on the CeNi 0.8Pt0.2 dense Kondo ferromagnet has been studied by means of magnetic and electrical resistivity measurements. The evolution from Kondo ferromagnetic behaviour to a non-magnetic ground-state regime is interpreted according to the theoretical Kondo lattice model. Anomalies in the temperature dependence of the electrical resistivity such as those observed in CeSi 1.85 are also found in this system.
