It was found that introducing Cu into Pd-site of CePd2Al 3 drives down the antiferromagnetic ordering temperature and brings about a ferromagnetic-like state, then further introduction leads to a revival of the antiferromagnetic state again. The nature of the conduction electron band changed by Cu plays an essential role in such Ce(Pd1-xCu x)2Al3 system. Focusing on the Cu-poor regime of x≤0.1, we found from specific heat results that TN decreases rapidly with growing Cu concentration, while the value of C/T at low temperatures is enhanced gradually until even below magnetic phase transition temperature. This system presents a complex magnetic interaction contrasted with the analogous Ce(Pd1-xNix)2Al3 system.
