Abstract
We have studied U3Si2 by means of the heat capacity, electrical resistivity, Seebeck and Hall effects, and thermal conductivity in the temperature range 2-300â¯K and in magnetic fields up to 9â¯T. All the results obtained point to delocalized nature of 5f-electrons in this material. The low temperature heat capacity is enhanced (γelâ¯â¼â¯150â¯mJ/mol-K2) and shows an upturn in Cp/T (T), characteristic of spin fluctuations. The thermal conductivity of U3Si2 is â¼8.5â¯W/m-K at room temperature and we show that the electronic part dominates heat transport above 300â¯K as expected for a metallic system, although the lattice contribution cannot be completely neglected.
