Fig. 3

a A comparison of THz emission between Mn2Au (red), Mn2Au/Pt (purple), NiO/Pt (cyan), and FeRh (green). The pump fluence of the laser pulse is 12 uJ mm–2 and the inset shows the very weak emission of FeRh and THz signal of Mn2Au is scaled down for 50 times. b The THz emission from the Mn2Au single layer shows no dependence on the magnetic field H (4 kOe).
