The correlation effects of the Ce 4f shell with extended valenz-band electrones are usually described in the framework of the Anderson model. These correlations are the most importend mechanism for description of magnetic properties of Ce- compounds. Here the electronic as well as the magnetic properties of Ce/Fe interface were studied by means of magnetic dicroism and Spin-resolved Photoemission. Obtained experimental results were treated by LSDA calculations and periodic Anderson model.
