Abstract

We performed soft x-ray resonant magnetic reflectivity experiments on [FeCo/Pd]n super-lattice films to study the depth profile of magnetization near the interface. From the analysis of the reflectivity measured at the Fe-L IIIabsorption edge, we obtained the magnetization profiles for the samples with different FeCo layer thicknesses. The profiles can be divided into three different zones: (A) Mixed region at the Pd interface where the magnetization decreased due to the structural randomness, (B) Enhanced region where the magnetization increased, and (C) Non-enhanced region. We estimated the thickness where the FeCo magnetization is enhanced by the adjacent Pd layer is about 4 atomic monolayers.
