Figure 8
Intensity asymmetry ratio (a) and X-ray resonant scattering (b) at the Co K edge for the multilayer structure (Co1 nm/Gd0.2 nm)40 over SiO2. The beam of about 70% circularly polarized photons reaches the sample with a grazing angle of 0.49°. The absorption cross section for Co metallic foil in transmission mode is also shown in (b). |
