摘要：

Bragg peaks are observed in difference resonant specular reflectivity signals from a GdCo/Ag multilayer in a flipping magnetic field for circularly polarized X-rays. The element-specific X-ray scattering at the L-3 absorption edge of Gd directly evidences layers of magnetically ordered Gd ions stacked at a regular spacing of the multilayer 51 Angstrom period. The Bragg peaks show a negative polarity, which is accounted for by the property of the resonant magnetic-charge interference scattering.
