Dynamics of magnetization reversal in thin films of amorphous rare earth-transition metal alloys are investigated. Using computer simulations for a two-dimensional square lattice of dipoles with nearest-neighbor exchange interaction and random axis anisotropy, the Landau-Lifshitz-Gilbert equation is numerically integrated to yield the static wall structure and its motion under an applied field. The simulated results show excellent agreement with theory in the special cases where analytic solutions exist.
