Magnetic Images (IMAGE) Osaka University Caption Time-dependent magnetic images of the (a)Gd26% and (b)Gd22% samples, respectively. In the Gd26% sample, clear spin reversal is observed. However, in the Gd22% sample, wave-like magnetization modulation propagated isotropically along the radial direction.
