Measurements of magnetic susceptibility, electrical resistivity and thermoelectric power have been made on the CeTIn system (T=Ni, Pd and Pt) with the hexagonal Fe 2 P-type structure. The results suggest that CeNiIn is an intermediate valence compound with Kondo-like anomalies in resistivity ρ m (T), and CePdIn is a heavy fermion compound with doubie-peak structures in both ρ m (T) and S(T) and exhibits an antiferromagnetic order at T N =1.8 K, whereas CePtIn is a heavy fermion peak in ρ m (T) and shows no magnetic and superconducting transitions.
