| Popis: | Transition processes in nonequilibrium micromagnetic structures that represent regions of various types of asymmetrical vortex domain walls with closely spaced transition structural elements, including vertical Bloch lines (VBLs), singular points, and clusters consisting of VBLs and singular points, have been studied by the method of three-dimensional numerical simulation of the magnetization behavior. The realization of various scenarios of dynamic behavior, including the annihilation of transition elements accompanied by the liberation of energy and the initiation of wave processes, has been shown to be possible. The simulation was performed for the case of magnetically uniaxial ferromagnetic films with an easy axis parallel to their surface with exact allowance for the inhomogeneous exchange, magnetoanisotropic, and magnetostatic interactions. © 2013 Pleiades Publishing, Ltd. |
