为了研究具有反铁磁层间耦合的Fe/Au(001)多层膜中Au层的磁结构，测量了小角区不同磁衍射角下的共振X射线磁散射(RXMS)强度与X射线能量的关系。利用先前从RXMS角度扫描确定的共振磁散射长度的深度调制，很好地再现了观察到的光谱。这支持了共振磁散射长度的深度调制对应于Au自旋极化的深度分布的假设。通过对能量相关的RXMS谱的详细分析，再次证实了角扫描测量发现Au层中存在均匀分布的自旋极化分量。
X-ray energy dependence of the resonant X-ray magnetic scattering (RXMS) intensity was measured at several magnetic diffraction angles in the small angle region in order to investigate the magnetic structure of the Au layer induced in the Fe/Au(001) multilayer with antiferromagnetic interlayer coupling. The observed spectra are reproduced well using the depth modulation of the resonant magnetic scattering length previously determined from the angle scan of RXMS. This supports the assumption that the depth modulation of the resonant magnetic scattering length corresponds to the depth profile of Au spin polarization. The existence of the uniformly distributed spin polarization component through the Au layer, which was found with the angle scan measurement, is confirmed again from the detailed analysis of energy-dependent RXMS spectra.
