Electrical resistivity {rho} and magnetic properties of light rare-earth Heusler single crystals RInCu{sub 2}, R=La, Pr, Nd, and Sm, have been measured in the temperature range 1.3--300 K. No anomalies due to magnetic transitions were found in the temperature dependence of {rho} and magnetic susceptibility {chi} above 4.2 K. Pr and Nd Heusler compounds have large negative paramagnetic Curie temperatures {minus}19 and {minus}29 K, respectively. The temperature dependence of {chi} is discussed on the basis of the crystalline field effect. For Sm compound, {chi}({ital T}) is discussed by means of Van Vleck paramagnetism.
