Simple model to calculate surface magnetization from spin-polarized metastable deexcitation spectroscopy: Fe/Ag(100)

A simple model has been introduced to extract effective charge and magnetization densities at surface from spin-polarized metastable deexcitation spectroscopy data. The model has been applied to the case study of a 10-ML film of Fe deposited at T=120 K on Ag(100). The charge and magnetization densities which have been calculated compare well with the experimental and theoretical data available on this system. In particular, the energy shift of 0.3 eV between the majority and the minority densities of states near the Fermi edge detected by spin-polarized photoemission is reproduced with high accuracy.
