Fig. 4: Magnetization reversal in 250 u.c.

SRO-30 film imaged by MFM. The magnetization reversal process exhibits two-step behavior: a–e is the first step; f–i is the second step. j Field-dependent Hall resistance measured by transport (blue) at 50 K and that estimated by MFM images (magenta) show similar behavior. The MFM images were taken at 50 K.
