The results of an investigation of the superconducting and normal state physical properties of (LaNd)Sn3 alloys are reported. Superconducting state data are presented describing the depression of the superconducting transition temperature Tcwith Nd impurity concentration, the reduction of the reduced jump in heat capacity ΔC/ΔC0 with decreasing reduced superconducting transition temperature Tc/Tc0, and the pressure dependence of Tc. Normal state data for the temperature dependences of the magnetic susceptibility and heat capacity demonstrate the importance of crystalline electric field effects in the physical behavior of (LaNd)Sn3 alloys and indicate that Nd interimpurity magnetic interactions and possibly a small amount of Nd-Sn antisite disorder are manifested in the experimental results. Theories based on an isotropic exchange depairing model are unable to give a satisfactory account of all of the experimental data, suggesting that the physical properties of(LaNd)Sn3 alloys may be modified by processes involving the orbital exchange scattering of host conduction electrons by the Nd impurities.
