Here, we have studied U3Si2 by means of the heat capacity, electrical resistivity, Seebeck and Hall effects, and thermal conductivity in the temperature range 2-300 K and in magnetic fields up to 9 T. All the results obtained point to delocalized nature of 5f-electrons in this material. The low temperature heat capacity is enhanced (γel ~ 150 mJ/mol-K2) and shows an upturn in Cp/T (T), characteristic of spin fluctuations. The thermal conductivity of U3Si2 is ~8.5 W/m-K at room temperature and we show that the lattice part of the total thermal conductivity is small, with electrons dominating heat transport above 300 K.
