摘要：

The electrical resistivity, magnetic susceptibility and specific heat of a ternary intermetallic compound CeNi2Al5 have been measured. It is found that CeNi2Al5 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.
