测量了三元金属间化合物CeNi2Al5的电阻率、磁化率和比热。发现CeNi2Al5是一种新的致密近藤化合物，其Neel温度为2.6K.电阻率的温度依赖性在4.0 K处有一个宽峰，反映了近藤散射的相干性。当考虑到由短程有序延伸的尾面积时，由熵等于Rln2的结果，确定Ce离子的基态为双峰态.在强磁场中观察到自旋翻转，并粗略估计了磁相图。
The electrical resistivity, magnetic susceptibility and specific heat of a ternary intermetallic compound CeNi 2 Al 5 have been measured. It is found that CeNi 2 Al 5 is a new dense Kondo compound with the Neel temperature of 2.6 K. The temperature dependence of the resistivity has a broad peak at 4.0 K, reflecting the coherence of the Kondo scattering. The ground state of the Ce ions is determined to be a doublet from the result that the entropy equals R ln 2 when we include the area of a tail extended by the short-range order. A spin-flip is observed in high magnetic field, and a magnetic phase diagram is roughly estimated.
