Abstract

We report on resistivity, specific heat and magnetization measurements carried out on the novel compound CeCu₂Mg, which crystallizes in the hexagonal GdPt₂Sn structure type. CeCu₂Mg shows typical Kondo lattice features, with a very high γ value of about 1000mJ/mol K²and a characteristic temperature T_K of about 5 K. Long-range magnetic order does not set in above 1.5 K.

Keywords: CeCu₂Mg; Heavy fermion; Kondo lattice
