Magnetization and electrical resistivity measurements on CeCuAl3 single crystal

Abstract

We present the electronic properties of CeCuAl3 studied by means of magnetization and electrical resistivity measurements in well characterized single crystal. CeCuAl3 crystallizes 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.
