Figure 3

Domain wall propagation for two different coercive field gradients. Propagation of the DW in the region with small (a) and high (b) coercive field gradient, i.e., for areas A and B marked in Figure 4, respectively. (c) Positions of the DW [x_DW(H_ext) − x_DW(H_ref = 21.9 kA/m)] and [y_DW(H_ext) − y_DW(H_ref = 21.9 kA/m)] relative to its position for a reference field pulse of 21.9 kA/m as a function of field pulse amplitude H_ext. The scales in (a) and (b) are the same.
