Abstract
The temperature dependence of the electrical resistivity, thermopower, specific heat, susceptibility and magnetization of CeCuAl3 are presented. CeCuAl3 behaves as a Kondo lattice system with antiferromagnetic ground state properties (TN∼2.8 K). The valency of Ce in this tetragonal compound is close to 3 and the overall crystal field splitting found from our results is about 150 K. The Kondo temperatureTK in the crystal field ground state, estimated from the magnetic susceptibility and the specific heat, is of the order of 8 K.
