Structure, magnetic and transport properties of polycrystalline Nd0.5 Sr0.4Pb0.1Mn1-xFexO3 Com pounds were experimentally studies. Single-phase samples obtained in the range x=0.0—0.1 Fe Content. There are no appreciable structure changes for introduction Fe. Mn-site doping favous a reduction magnetic/resistive transport, at rate ～16K 6% Fe, an elevated resistivity. Metal-insulator transition disappears when content exceeds ～0.08. The enhanced effects Nd0.5Sr0.4Pb0.1Mn1-xFexO3 can be ascribed to presence which influences concentration mobile electron eg restrain double exchange interaction compounds.
