We present a systematic study of the impurity scattering effect induced by Pd dopants in the superconductor SrPt3P. Using a solid-state reaction method, we fabricated the Pd-doped superconductor Sr(Pt1-xPdx)(3)P. We found that the residual resistivity rho(0) increases quickly with Pd doping, whereas the residual resistance ratio (RRR) displays a dramatic reduction. In addition, both the nonlinear field-dependent behavior of the Hall resistivity rho(xy) and the strong temperature dependence of the Hall coefficient R-H at low temperature are suppressed by Pd doping. All the experimental results can be explained by an increase in scattering by impurities induced by doping. Our results suggest that the Pt position is very crucial to the carrier conduction in the present system.
