Micromagnetic softwares based on finite difference (FD) approximation are commonly used in the community, meaning that the magnetic system is divided into regular orthorhombic cells. In these the implementation of FD solvers in time and in space for the Landau-Lifshitz-Gilbert (LLG) equation is... > suite
Magnetostatic interactions are important however difficult to tackle due to their long range. In homogeneous systems the concept of demagnetizing factors, assuming uniform magnetization, has long and widely been used. The anisotropy of demagnetizing factors is directly related to the anisotropy field, coercive field and thermal stability for elements small enough to remain reasonably single-domain. We extended this concept to synthetic antiferromagnets (two stacked layers magnetized in opposite directions), which are widely used as elementary bricks in spintronic devices, and deliver analytical formulas and a discussion of the resulting physics.
Spin electronics devices are based on the control of magnetization in nanometer-sized elements, so that the knowledge of the spatial distribution of magnetization is of prime importance. Owing to the continuous decrease of the size of devices while the power of computers increases, most systems... > suite
