摘要：

We have prepared and examined the resistivity and magnetic susceptibility of a series of ternary compounds with composition Ce(8)Pd(24)M, 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 trivalent cerium. The lanthanum compound behaves as a simple metal in resistivity and has a small, negative susceptibility at 295 K. All the cerium compounds but the gallide exhibit antiferromagnetic ordering below 10 K. Metallic behaviour is observed for all. The properties of the stannide, plumbide, antimonide and bismuthide reflect some weak interactions with crystal-field-split cerium states above 30 K and changes in slope at low temperature coincident with the second-order antiferromagnetic phase transitions. Resistivities for the gallide and indide display broad features near 15 and 50 K, respectively, suggesting that a strong Kondo interaction is present in these materials.
