Abstract

Spin-dependent absorption spectroscopy as a method to study the spin density of unoccupied states is demonstrated in case of the Fe K-edge and Pt L_2,3-edges in the ferromagnetic alloy Fe₈₀Pt₂₀. Large relative spin-dependent parts of the absorption coefficient μ_c/μ₀∼+23% at the Pt L₂- and μ_c/μ₀∼-12% at the Pt L₃-edges have been found. The μ_c/μ₀-spectra are interpreted in terms of spin density profiles of p- and d-projected states near the Fermi level populated in the absorption process and are compared with results of spin-resolved band-structure calculations.
