Schematic explanation of the model conditions. The wall jumps from the releasing point to the next pinning site.
Scheme of the dependence of the domain-wall velocity on the position: (a) the velocity of the domain wall interacting with the pinning sites and and (b) Barkhausen signal, corresponding to the same domain wall, filtered.
