Abstract
The dynamic rearrangement of the structure of vortex domain walls (DWs) in films with uniaxial in-plane anisotropy has been examined based on two-dimensional micromagnetic model simulation. The optimum computational region has been chosen; grids with up to 270 × 75 cells 3 nm in size have been used. The scenarios of dynamic rearrangement of the DW structure in strong fields (up to 450 Oe) and in films with thicknesses exceeding 100 nm have been revealed for the first time. The emergence of multivortex instantaneous distributions of magnetization upon an increase in the film thickness and the external field intensity have been established. The dependence of the critical field on the film thickness has been refined.
