Figure 3
Prompt electronic (a) and delayed nuclear (b) reflectivity curves as well as stroboscopic SMR spectra (c)–(e) of a MgO(001)/[57Fe/Cr]20 antiferromagnetic multilayer at various angles indicated by arrows in (b). The consecutive Fe layer magnetizations are aligned parallel/antiparallel with to the SR beam. Vertical dotted lines in panels (c)–(e) indicate the centre of the zero and ±1-order stroboscopic bands separated by ∊ ≃ 10.93 mm s−1 for the applied observation window period. |
