MicroMAG-2D (version 2.0) system has been developed for investigations of statics and dynamics of two-dimensional 180° domain walls in the thin ferromagnetic films with arbitrary uniaxial anisotropy. This system is intended for developers of magnetic memory devices, physicists (experimentators and theoreticians), and may be used for illustration at high school (university) educational process. Static structure is a result of solving of nonlinear variational micromagnetic problem with magnetostatic interaction. Domain wall dynamics is computed by direct integration of Landau–Lifshits–Gilbert equation. Computational method used fast algorithm for demagnetization field and unconditionally stable scheme for temporal integration. Domain wall is keeping in the center of computational region by shadowing method.1 MicroMAG-2D system consists of (a) initial data generation module; (b) computational module; (c) Editor/Viewer module; (d) Animator module. System requirements: IBM PC AT compatible (Intel 80386/387 or 80486 processor).
