Antiferromagnetic transitions in the Kondo lattice system Ce2Ni3Ge5
PhysRevB_62_8950.pdf 74.4 KB
Our investigation of Ce2Ni3Ge5 by means of transport, specific heat and magnetization measurements shows that the compound is a Kondo lattice system exhibiting two antiferromagnetic transitions at TN1=5.1 K and TN2=4.5 K. An analysis of the transport and specific heat data suggests that the Kondo energy scale kBTk is of the order of kBTN. The resistivity and heat capacity data below 4 K are suggestive of the appearance of a spin-wave gap. The compound exhibits giant magnetoresistance at low temperature. The crystal field splitting is estimated to be about 180 K.
