摘要：

The effects of the Pt content in CoCrPt thin films on the appearanace of the near-edge structure of the Cr and Co L2,3 absorption edges were studied using parallel electron energy loss spectroscopy (PEELS). These reflect local changes in the 3d band of the material. It was found that addition of Pt leads to local fluctuations in the 3d band occupancy in CoCrPt films which causes a decrease of the number of 3d electrons per Co atom. An increase of the L3 to L2 white lines intensities ratio on the L2,3 Co edge with Pt content probably indicates an increase of the magnitude of exchange interactions in the CoCrPt thin films.
