ELECTRIC AND MAGNETIC-BEHAVIOR OF CE(8)PD(24)M COMPOUNDS WITH M=(GA,IN,SN,PB,SB AND BI)

We have prepared and examined the resistivity and magnetic susceptibil ity of a series of ternary compounds with composition Ce(8)Pd(24)M, wh ere 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 behav es as a simple metal in resistivity and has a small, negative suscepti bility at 295 K. All the cerium compounds but the gallide exhibit anti ferromagnetic ordering below 10 K. Metallic behaviour is observed for all. The properties of the stannide, plumbide, antimonide and bismuthi de reflect some weak interactions with crystal-field-split cerium stat es above 30 K and changes in slope at low temperature coincident with the second-order antiferromagnetic phase transitions. Resistivities fo r the gallide and indide display broad features near 15 and 50 K, resp ectively, suggesting that a strong Kondo interaction is present in the se materials.
