Abstract ： Co-Nb/Pd multilayer films with different thicknesses of Co-Nb layers have been prepared by rf sputtering. X-ray diffraction showed that the Co-Nb layers for all samples were in amorphous state. Magnetic measurements showed that the Pd atoms near the Go-Nb layers are polarized by Co atoms. The total thickness of polarization for each Pd layer is about 3.2Å. A perpendicular easy axis in Co-Nb/Pd films can be obtained when the Co-Nb layers are very thin.
