[en] The fcc-Ce₃In compound is presented as the best available approximation to reproduce the main magnetic properties of γ-Ce at low temperatures, where such pure phase does not exist. The electronic specific heat shows a maximum at 18K and an anomaly at 2.2K, with an entropy of 0.8Rln at 32K. The susceptibility shows a broad maximum at 1.8K, while in the magnetization there are no trace of ordering up to 18 Tesla at 1.5 and 4.2K. The experimental results are interpreted as governed by a quadruplet crystal field ground state, which undergoes a quadrupolar transition at 18K. At lower temperatures a heavy fermion ground state developes with C_el/T = 500 mJ/Ceat.K² for T → 0 and χT/C_el = 0.ll emu K/J for T < 5K. (Author)
