Fig. 2. Schematic of the conducted OISTR experiment.
(A) Experimental setup. An EUV probe pulse investigates the element-specific magnetization dynamics in Fe50Ni50 triggered by an IR pump. (B) Magnetic asymmetry of Fe and Ni plotted as a function of the photon energy. The shaded green and blue energy ranges mark the energy range that is commonly integrated in an absorption edge experiment to obtain the total magnetization.
