Multi-scale modelling of magnetization dynamics — •Andrea De Lucia, Mathias Kläui, and Bejnamin Krüger — Institut für Physik, Johannes Gutenberg Universität, Mainz

A Multi-scale Magnetization Dynamics Simulation scheme was developed and applied to systems with special spin structures and properties. The MicroMagnum simulator was used as starting point and expanded to include a Multi-scale approach. The software selectively simulates different regions of a ferromagnetic sample employing the most suitable discretization and model according to the properties of each region. Simulating magnetization dynamics in a Multi-scale environment allows one to rapidly evaluate the Landau-Lifshitz-Gilbert equation in a mesoscopic sample with nanoscopic accuracy where needed. Possible application of this software include Skyrmion Dynamics, Domain Wall motion and Spin Wave generation.
