Left: static resonant magnetic reflectivity spectra measured for opposite magnetic fields (±10 mT) on a Ho3Fe5O12 sample at 300 K and a 10–20° θ–2θ geometry. Right: schematic view of the time-resolved reflectivity geometry together with the transient demagnetization of the Ho3Fe5O12 measured at the Fe L3 edge with 50 ps time resolution upon pumping the sample at 400 nm wavelength (data taken from Radu et al., 2014). |
