Reduced Model in Thin-film Micromagnetics
The full minimization problem in micromagnetics due to Landau and Lifschitz is, from a numerical point of view, very complex. In [7] a reduced model in thin-film micromagnetics has been proposed and analyzed with focus on a distributional point of view. In contrast, we present a functional analytic framework which is more suitable for numerical analysis. Well-posedness of the model problem in t...
متن کاملVirtual Micromagnetics: A Framework for Accessible and Reproducible Micromagnetic Simulation
Computational micromagnetics requires numerical solution of partial differential equations to resolve complex interactions in magnetic nanomaterials. The Virtual Micromagnetics project described here provides virtual machine simulation environments to run open-source micromagnetic simulation packages [1]. These environments allow easy access to simulation packages that are often difficult to co...
متن کاملExchange Energy Formulations for 3D Micromagnetics
Exchange energy is especially sensitive to the numerical representation selected. We compare three discretized exchange energy formulations for 3D numerical micromagnetics on rectangular grids. Explicit formulae are provided for both Neumann and Dirichlet boundary conditions. Results illustrate the convergence order of these methods as a function of discretization cell size and the effect of ce...
متن کاملEffect of cell size in calculating frequencies of magnetic modes using micromagnetics: Special role of the uniform mode
Using the time evolution of the dynamic magnetization, we study the frequencies of spin excitations in small ferromagnetic bars with particular attention to the uniform mode. The calculation is done using micromagnetics, and the frequency of various modes is found as a function of the cell size used in the calculation. We find that the uniform mode and some standing spin-wave modes are relative...
