Time-dependent polar Kerr images taken under (a) a vacuum, (b) 0.2 bar H2, (c) 0.6 bar H2 and (d) 0.8 bar H2. The four series of Kerr images were taken over the same area, at 2, 3, 4, and 6 s after the application of the reverse magnetic field, which was approximately 0.92 times the magnetic coercivity field in each condition. The image size was 450 × 450 μm2.
