Figure 5: MD structure changes by the fm-sweep for a given initial state.
From: Adaptive microwave impedance memory effect in a ferromagnetic insulator
(a) MD images observed during the initial fm-sweep, where initial MDs that remained after the fm-sweep were indicated by red arrows. (b,c) MD images observed during the first (b) and last (10 times; c) fm-sweep, where three MDs that showed distinct reversible changes were indicated by A1–A3. (d) Averaged difference of TR-MO intensity (ΔTR-MO) between the fm=0.1 and 3.0 GHz, where 20 images were averaged for each fm. (e) The line-profiles of TR-MO intensity from A2 to A1 (indicated by arrow) for various fm. (f) Absolute values of spatial gradient of averaged TR-MO images measured at fm=0.1 and 3.0 GHz. (g) Local average change of the spatial gradient values around A3 (indicated by dotted circle).
