摘要：

We synthesize a set of Pd-doped polycrystalline samples PdxNdSeTe;and measure their physical properties.Compared with pure NdSeTe;,the charge density wave（CDW） order is continuously suppressed with the Pdintercalation.Bulk superconductivity first appears at x=0.06 with T;nearly 2.5K,coexisting with a CDW transition at 176 K.Further Pd-doping enhances T;,until it reaches the maximum value 2.84 K at x=0.1,meanwhile the CDW transition vanishes.The upper critical field for the optimal doping sample Pd;NdSeTe;is determined from the R-H measurement,which is estimated to be 0.6 T.These results provide another kind of ideal compound for studying the interplay between CDW and superconductivity systematically.
