Abstract:

Based on the numerical solution of Landau-Lifshitz equations, the nonlinear dynamic behavior of vortex-like domain walls in films with in-plane anisotropy has been investigated in external magnetic fields H significantly exceeding critical fields H (c) , above which the stationary motion of domain walls is replaced by nonstationary (periodic or aperiodic) motion. A method has been proposed for the detection of complex aperiodic dynamics of structural rearrangements of domain walls, which is based on the construction of diagrams of the dependences of the tilt angle of the magnetization M with respect to the plane of the domain wall in some of its points on the corresponding angle in other points. It has been found that these diagrams significantly change with variations in the external magnetic field applied along the easy axis of magnetization in the range H > H (c) . It has been shown that the pattern of these changes is similar to the scenario of the Feigenbaum transition to dynamic chaos.
