Ga and Pt NMR measurements have been carried out for two isomorphs compounds, UPtGa 5 and UNiGa 5 , which exhibit different magnetic structures below T N . Knight shift K measurements in the paramagnetic region are reported here. The transferred hyperfine coupling constants at Ga and Pt sites are determined. The temperature independent part K 0 of K , which probes the conduction electron polarization at the ligand site, has been successfully evaluated. A nearly identical conduction electron structure in the paramagnetic region is suggested for these two compounds. The origin of the different magnetic structures is discussed.
