Extended Data Fig. 7: Dynamics of pump-induced MOKE rotation and ellipticity signals.

From: Photo-induced high-temperature ferromagnetism in YTiO3

Extended Data Fig. 7

Comparison of the pump-induced MOKE rotation (grey) and ellipticity (pink) angles. The two curves overlap, suggesting that the signal represents pure magnetization dynamics, rather than pump-induced changes in the magneto-optical coefficient. These measurements were taken with 9 THz pump excitation at T = 10 K, and H = ±2 T, but all other pump wavelengths, temperatures, and fields show similar behavior.
