【 摘 要 】

We present the electronic properties of CeCuAl3studied by means of magnetization and electrical resistivity measurements in well characterized single crystal. CeCuAl3crystallizes in the ordered non-centrosymmetric tetragonal BaNiSn3-type structure. The antiferromagnetic phase transition around 2.5 K was revealed by magnetization measurement. The clearly pronounced anomaly on electrical resistivity data was observed the same temperature. A relatively strong magnetocrystalline anisotropy with the magnetization easy-basal plane and hard c-axis was observed. The ferromagnetic correlation stronger along the c-axis than in the basal plane were found in paramagnetic state.
