Figure 6
Magnetic asymmetry ratio (dots) recorded for the CoPt3 alloy at the Pt L3-edge as a function of the offset angle of the X-ray phase retarder crystal. The asymmetry ratio is compared with the calculated circular polarization rate, assuming bandwidths of ΔE/E = 1.1 × 10−4 (solid line) and 0.5 × 10−4 (dotted line). |
