摘要：

We study the X-ray magneto-optical Faraday effect at the Fe L-2,L-3-edges of ferromagnetic Fe, FeNi and FePt. Ab initio calculations based on the local approximation to spin density functional theory provide a very good explanation of the X-ray Faraday spectra measured at the Fe L-edge of FeNi films. A small, yet non-negligible, improvement of the agreement with the experimental X-ray Faraday spectra is obtained when the exchange splitting of the 2p core states is taken into account.
