a, b The variation of the (−0.5, 0, 0.62) magnetic peak before and after pump excitation (1000 ps, 400 nm) with 777.3 eV and 778.9 eV at 23 K. The superstructure peaks are subtracted from the data. The grey shade indicates the change in intensity caused by photoexcitation. Solid lines are fit using a Lorentzian function. Error bars represent Poisson counting error. c, d Magnetic intensity normalized by laser-off data as a function of time delay with 777.3 eV (c) and 778.9 eV (d) at 23 K. The blue and red lines display the results of fitting, corresponding to pump fluence of 0.37 and 1.31 mJ/cm2 respectively.
