对三元金属间化合物CeNiAl 4的电阻率、比热容和磁化率进行了实验研究。结果表明，CeNiAl 4是一种新的处于价态涨落区的致密近藤化合物，在1.6K以上CeNiAl 4是稳定的.外推到0 K时的磁化率χ 0和电子比热系数γ 0分别为5.6×10 - 3emu/mol和204 mJ/mol·K2。近藤温度T K估计为67 K或86 K。
Experiments of electrical resistivity, specific heat and magnetic susceptibility of a ternary intermetallic compound CeNiAl 4 have been carried out. It is found that CeNiAl 4 is a new member of the dense-Kondo compounds in the valence-fluctuation regime and that CeNiAl 4 is nonmagnetic above 1.6 K. The susceptibility χ 0 and the electronic specific heat coefficient γ 0 which are extrapolated to 0 K are 5.6×10 -3 emu/mol and 204 mJ/mol·K 2 , respectively. The Kondo temperature T K is estimated to be 67 K or 86 K.
