The magnetic properties of Fe-Pd multilayers are strongly affected by the high magnetic polarization of Pd. The origin of the magnetization of Pd in contact with Fe is examined. We found that a surface Pd(100) photoemission structure persists upon preparation of 1 and 2 monolayers Fe. Comparison with an ab initio calculation identifies this structure as a state distributed equally between the Fe and the adjacent Pd layer. Spin analysis of the photoelectrons shows that this state is magnetic, and the calculation reveals that it contributes to the large Pd moment at the interface of 0.32μB.
