Fig. 3: Magnetization reversal in 75 u.c.

SRO-35 film imaged by MFM. The magnetization reversal process exhibits triple-step behavior: a–f are the first step; g, h are the second step; i–l are the third step. m Rxy-H loop measured by transport (red) and estimated by distribution of up and down domains in MFM images (purple) shows similar behavior. The MFM images were taken at 50 K.
