Fig. 2 Transient Kerr Rotation Signals (IMAGE) Science China Press Caption These are yransient Kerr rotation signals of the uncoated LSMO film and the LSMO films coated with 3- and 20-nm-thick BFO layers under external magnetic fields of 0.2 T (a), 0.4 T (b), and 0.6 T (c). The Fourier transforms of the signals shown in (a), (b), and (c) for external magnetic fields of 0.2 T (d), 0.4 T (e), and 0.6 T (f), respectively.
