Abstract
A new intermetallic compound Ce 2 AgIn 3 has been prepared and found to crystallize with the hexagonal CaIn 2 -type structure. We report the results of ac and dc magnetic susceptibility (χ ac and χ dc ), specific heat ( C ) and electrical resistivity (ρ) measurements on this compound. At around 1.8 K, the real part in χ ac shows a cusp and the nonlinear part in χ dc diverges, while there are no anomalies in both C and ρ. On the other hand, ρ increases slightly with decreasing temperature below 10 K and C / T at 0.5 K is large at 780 mJ/K 2 mol-Ce. These results indicate that Ce 2 AgIn 3 is a spin glass of good quality and also belongs to the heavy fermion system.Keywords
