N2 - Magnetic and structural behaviour of materials of composition RInCu2 (R = rare earth) were investigated. All the compounds (R = La-Lu) were found to be isotypic and to crystallize with the Heusler L21 type structure. The magnetic behaviour of the compounds was studied in the temperature range 2-300 K. The RInCu2 (R = Sm, Gd, Tb, Dy) compounds are antiferromagnetically ordered at low temperatures TN = 12 K for GdInCu2, Ce in CeInCu2 is in a pure trivalent state. LaInCu2 is Pauli paramagnetic and LuInCu2 is diamagnetic. No superconductivity was observed for temperatures as low as 1.8 K. The observed magnetic properties result from indirect exchange interaction and crystal field effects and compared to the isomorphous MnInCu2.
