22. The reflectivity of FeRh at 800 nm is about 75%, which gives a lower value for the actual absorbed laser fluence.
23. The magnetization nucleation value is defined as the ratio between the XMCD signal measured at negative delays and the final XMCD value while the demagnetization value is defined as the ratio between the level of the rapid drop of the XMCD signal and the signal measured at negative delays.
24. XMCD measurement averages over the nucleated FM areas within a 1 mm probing x-ray spot. The size of these nucleated areas varies form 0.3 to 3 micrometers as deduced from static PEEM measurements.
25. We note that in the temperature range of the AFM-FM phase coexistence τ G measures a combination of magnetization growth and remagnetization (following the demagnetization) processes.
