The susceptibity of yttrium alloys, containing Tb ions of 0.60 at. % to 3.71 at. %, has been measured in the temperature region from 1.4°K to room temperature. A systematic deviation of the Neel points from the ξ^<2/3> dependence where ξ is the effective spin factor, was found. This deviation might be interpreted as due to the existence of a critical concentration of Tb ions for the appearance of a long range magnetic spin ordering. From the Curie constants, we obtain the effective magnetic moment of 10.8 μB per Tb ion, which is larger than that for a free Tb^<3+> ion of 9.72 μB. The exchange interaction parameter between the conduction electron and the rare earth ion is estimated to be +0.15eV, which agrees well with the results of the electronic transport phenomenon.
