概要

• 論文の詳細を見る

• A new intermetallic compound Ce_2AgIn_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 (X_<ac> and X_<dc>), specific heat (C) and electrical resistivity (ρ) measurements on this compound. At around 1.8 K, the real part in X_<ac> shows a cusp and the nonlinear part in X_<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 ,J/K^2mol-Ce. These results indicate that Ce_2AgIn_3 is a spin glass of good quality and also belongs to the heavy fermion system.
