Investigation of Self-Organisation Structures in Supersonic Dynamics of Domain Wall in Orthoferrites

摘要

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 di until d_(i+1). Incidentally, the domain wall velocity changing abruptly in the transitions between H_(i) is a bifurcation parameter.
