Pd1-xFex/Fe multilayers (MLs) with x=0,0.34,0.056,0.071 have been prepared by magnetron sputtering. The measurement of saturation magnetization in Pd/Fe MLs in the range of Pd thickness from 4to 18 ML shiows that the interlayer couplings are ferromagnetic and Ms possesses a long-range oscillation with a period of 4 ML Pd. The oscillation phase and period in Pd0.966Fe0.034/Fe and Pd0.944Fe0.056/Fe multilayers remain unchanged as compared with their reference Pd/Fe multilayers. A discussion is given about discrepancy between theory and experiments, concerning with whether a negative polarization of Pd in inner spacer and a long-range ferromagnetic oscillation appears in Pd/Fe systems.
