【 摘 要 】

We synthesized a series of Nb2Pd1-xRuxS5polycrystalline samples by solid-state reaction method and investigated systematically the Ru doping effect on superconductivity by transport and magnetic measurements. It is found that superconductivity is enhanced with Ru doping and the superconducting transition temperature (Tc) reaches a maximum of 6.86 K at x = 0.2. Ru doping is regarded as the hole-type doping similar to the case of Ir doping. The evolution of Tcmidwith Ru doping is compared with the case of Ir or Ag doping.
