Figure 2: Soap-bubble-like domain wall expansion.

From: Inertial displacement of a domain wall excited by ultra-short circularly polarized laser pulses

Figure 2

(a) Schematic sketch of soap-bubble-like extension of an elastic DW within a symmetrical cross under the application of a magnetic field: The domain wall stays pinned on the input corners until it reaches the cross centre (red half-circle) (Supplementary Note 1). (b) Differential MOKE images of domain configurations in case of a geometrically pinned DW in a 6 μm wide device at BA=0.25 mT (b) and after the field has been switched off (BA=0 mT) (c). (d) Bubble-like domain shape when subtracting c from b. Note that the DW switched back after the field has been switched off.
