Abstract : We have prepared and examined the resistivity and magnetic susceptibility of a series of ternary compounds with composition Ce8Pd24M, where M is one of Ga, In, Sn, Sb, Pb or Bi and the related composition La8Pd24In. All members of this series are cubic with effective cerium moments consistent with tri-valent cerium. The lanthanum compound behaves as a simple metal in resistivity and has a small, negative susceptibility at 295K. All the cerium compounds but the gallide exhibit anti-ferromagnetic ordering below 10K. Metallic behavior is observed for all. The properties of the stannide, plumbide, antimonide and bismuthide reflect some weak interactions with crystal-field-split cerium states above 30K and changes in slope at low temperature coincident with the second-order anti-ferromagnetic phase transitions. Resistivities for the gallide and indide display broad features near 15K and 50K, respectively, suggesting a strong Kondo interaction is present in these materials. jg p3
