Magnetic properties of Ce2CuIn3

We report measurements on magnetic properties of CeCuIn3 compound. Irreversibility of the ZFC-FC curves of the DC magnetic susceptibility (M/H) at low field, and the shift of the peak with the frequency in the AC susceptibility give evidences for spin glass (SG) behavior at freezing temperature of T-f = 2.1 K. In addition, the relative shift per frequency decade, Delta T-f/T-f Delta log v = 0.016, is similar to those reported for other spin glasses. We discuss the results in relation with the other isotypic, Ce2TX3 (T = Transition metal and X = Si, Ge and In). The interplay of disorder and frustration within hexagonal Caln, type of structure and competition between RKKY interaction and Kondo effect are suggested as the main causes for the arising magnetic ground state.
