摘要：

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 T-N1 = 5.1K and T-N2 = 4.5 K. An analysis of the transport and specific heat data suggests that the Kondo energy scale k(B)T(K) is of the order of k(B)T(N). 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 held splitting is estimated to be about 180 K.
