Investigation of self-organisation structures in supersonic dynamics of domain wall in orthoferrites

With the help of laser beam pulse of duration 25-30 ps it is found that the domain wall motion at supersonic velocities in orthoferrites complies with regularities that take place in dynamic self-organizing systems. It is also observed that transition between two neighboring ranges from H_i until H_i+1 in the dependence V(H) is accompanied by a reduction in size of multidimensions on the domain wall, from d_i until d_i+1. Incidentally, the domain wall velocity changing abruptly in the transitions between H_i is a bifurcation parameter.
