CHAOTIC DYNAMICS OF PERIODICALLY DRIVEN DOMAIN-WALLS IN MAGNETIC GARNET-FILMS

The motion of domain walls in thin garnet films was investigated numer ically using Slonczewski's equations of wall motion for the case of pe riodic drive field. The type of the wall motion was analyzed by observ ation of phase trajectories and spatio-temporal diagrams. It was found that depending on the period and amplitude of the drive field the mot ion of the wall is periodic or chaotic, reflecting the character of th e dynamical processes connected with horizontal Bloch lines in the wal l.
