Abstract
The results of electrical resistivity (1.4-300K) measurements on the alloys, CeNixGa4−x (x=0.5, 0.625, 0.75, 0.875 and 1.1) and CeCuxGa4−x (x=0.5, 1.0, 1.25 and 1.5) are reported. The results show the existence of magnetic ordeing below 6K for Ga rich alloys (among the compositions investigated), whereas increasing the Ni and Cu content depresses magnetic ordering. Considering that the isothermal magnetization below 4.5K as a function of applied magnetic fields tends to saturate, Ga rich compositions are ferromagnetic. θ data exhibit distinct anomalies characterizing Kondo effect and hence these alloys are ferromagnetic Kondo lattices.
