Magnetization and electrical resistivity measurements on CeCuAl₃ single crystal

We present the electronic properties of CeCuAl 3 studied by means of magnetization and electrical resistivity measurements in well characterized single crystal. CeCuAl 3 crystallizes in the ordered non-centrosymmetric tetragonal BaNiSn 3 -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.
