Description

Transport, thermal, and magnetic data for the heavy electron system URu2Si2 indicate that a charge- or spin-density-wave transition opens an energy gap of approx.11 meV over a portion of the Fermi surface below T0roughly-equal17.5 K and demonstrate that bulk superconductivity occurs below T/sub c/roughly-equal1.5 K. The pressure dependences of T0 and T/sub c/ support this interpretation. The unusually large initial slope of the upper critical magnetic field (9.2 T/K) is consistent with the high values of the electronic-specific-heat coefficient and the electrical resistivity
