Soft-x-ray small-angle scattering as a sensitive probe of magnetic and charge heterogeneity - art. no. 092401

Cobalt 2p resonant scattering from Co/Pt multilayers with perpendicular ani sotropy results from magnetic and chemical heterogeneity having very differ ent length scales. Magnetic and chemical scattering result from domains and the crystalline grain structure, respectively, as confirmed by field-depen dent scattering and by imaging using magnetic x-ray and atomic force micros copy. Magnetic and charge scattering have distinct energy spectra that are quantitatively modeled using measured Co scattering factors. Domain and che mical correlations remain uncoupled throughout the reversal process.
