摘要：

We report measurements of the specific heat C-p(T), electrical resistivity rho(T) and magnetic susceptibility chi(T) of hexagonal CePd2In at low temperatures. Anomalies in C-p(T), chi(T) and rho(T) at T = 1.23 K, indicate a phase transition, most likely to an antiferromagnetically-ordered phase. The electronic entropy reaches R ln2 per mole Ce at 9.2 K, suggesting that the phase transition involves a doublet state. The ordered phase coexists with moderately correlated itinerant electrons.
