We report 31 P and 29 Si NMR in single crystals of URu2Si2−xPx for x = 0.09 and x = 0.33. The spectra in the x = 0.33 sample are consistent with a homogenous commensurate antiferromagnetic phase below TN ∼ 37 K. The Knight shift exhibits an anomaly at the coherence temperature, T * , that is slightly enhanced with P doping. Spin lattice relaxation rate data indicate that the density of states is suppressed for x = 0.09 below 30 K, similar to the undoped compound, but there is no evidence of long range order at this concentration. Our results suggest that Si substitution provides chemical pressure without inducing electronic inhomogeneity.
