Abstract
The pressure dependence of the superconducting transition temperature Tc up to 68 kbar and resistivity up to 18 kbar were measured on the ternary compound Lu5Rh4Si10. At ambient pressure, Lu5Rh4Si10 shows a metalliclike temperature variation of resistivity at temperatures higher than 160 K, exhibits an anomaly at 155 K, and undergoes a superconducting transition at 3.4 K. A tendency to suppress the resistive anomaly and enhance the superconducting transition temperature by the application of pressure was observed. In combination with molar-magnetic-susceptibility data, it is shown that the formation of a charge-density wave opens an energy gap which reduces the density of electronic states at the Fermi surface.
