Figure 4
Prompt electronic (a) and delayed nuclear (b) reflectivity curves as well as stroboscopic SMR spectra (c)–(e) of a [57Fe(2.6 nm)/Cr(1.3 nm)]20/MgO antiferromagnetic multilayer at various angles indicated by arrows. The consecutive Fe layer magnetizations are aligned perpendicular 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. |
