FIG. 1. (a) Sketch of the experimental setup. (b) Intensity dis- dis-tribution of a single x-ray pulse recorded by the sample camera (converging first order, after passing through the Co 76 Dy 24 thin film sample) and reference camera (diverging first orde
FIG. 2. Treated transmission signal image (see text) revealing the IR-pulse-induced magnetization dynamics of a thin Co 76 Dy 24 film in the presence of an out-of-plane applied field of 250 mT and an IR pump pulse intensity of 55 μ J
FIG. 3. (a) Non-normalized transmitted intensity as a function of pump-probe time delay recorded on a Co 76 Dy 24 film by averaging 500 pump-probe cycles (IR intensity of 55 μ J)
FIG. 4. Normalized demagnetization dynamics as a function of pump fluence recorded (a) on Co 76 Dy 24 (500 shots accumulated) and (b) on Co 86 Dy 14 (50 shots accumulated)
