Fig. 2: Optical pump-THz probe measurements of FenGeTe2 (n = 3, 5) films at different temperatures and fluences.

a Pump-probe data at 80 K and 5 mJ/cm2 for the four measured films over an extended time scale. b Pump-probe trace at different temperatures (heating from 80 K) for the 15 ML F3GT film. c Temperature evolution of the pump-probe trace at fixed probe delays 0, 1, and 2 ps of b). The arrows indicate the magnetic and Kondo lattice transition of F3GT. d Pump-probe data at 80 K and variable fluence for the 15 ML F3GT film. e Fluence evolution of the 80 K pump-probe trace of F3GT (15 ML) at fixed probe delays 0, 1, and 2 ps of d). The inset shows the extension at longer probe delays of d) for two fluences. Data error bars shown in panels c and d were obtained from the average and the standard deviation of 30 measured pump-probe traces, each one consisting of 100 acquisitions for each point.
