Partial restoration of clusters of vertical Bloch lines after a collision
Chetkin M. V., Parygina I. V., Savchenko L L.
Experiments show that, at a certain velocity of a domain wall in an iron garnet film, there can be a partial restoration of clusters of vertical Bloch lines after these clusters undergo a head-on collision. This result agrees with predictions of a numerical simulation. For this reason, the situation described here is considerably more general than that in the classical theory of solitons or in experiments on the collision of Josephson vortices. An attempt is made to determine the topological charge of a cluster from the experimental profile of a solitary wave of a bending of a domain wall with the help of the Slonczewski equations.
