Time-dependent longitudinal Kerr images taken under. (a) a vacuum, (b) 0.2 bar H2 and (c) 0.8 bar H2. The three series of Kerr images were taken over the same area, 1, 2, 3, and 6 s after the application of the magnetic field, which was 0.9 times the magnetic coercivity field in each condition. The image size was 450 × 450 μm2.
