垂直各向异性Co/Pt多层层的钴2p共振散射是由不同长度尺度的磁非均质和化学非均质引起的。磁散射和化学散射分别来自畴和晶体颗粒结构，这一点可以通过场相关散射和磁x射线和原子力显微镜成像来证实。磁散射和电荷散射具有不同的能谱，可以用测量到的Co散射因子进行定量建模。在整个逆转过程中，域和化学相关性保持不耦合。
Cobalt 2p resonant scattering from Co/Pt multilayers with perpendicular anisotropy results from magnetic and chemical heterogeneity having very different length scales. Magnetic and chemical scattering result from domains and the crystalline grain structure, respectively, as confirmed by field-dependent scattering and by imaging using magnetic x-ray and atomic force microscopy. Magnetic and charge scattering have distinct energy spectra that are quantitatively modeled using measured Co scattering factors. Domain and chemical correlations remain uncoupled throughout the reversal process.
