A multiscale approach for magnetic skyrmion simulations — •Thomas Brian Winkler1, Andrea de Lucia1,2, Kai Litzius1,2,3, Oleg Tretiakov4, Benjamin Krüger1, and Mathias Kläui1,21Johannes Gutenberg Universtät Mainz, — 2Graduate School of Excellence - Material Science in Mainz, Staudingerweg 9, 55128 Mainz, Germany — 3Max Planck Institute for Intelligent Systems, 70569 Stuttgart, Germany — 4Institute for Material Research, Tohoku University, Sendai 980-8577 Sendai

Simulations of magnetization dynamics in a multiscale Environment enable a rapid evaluation of the Landau-Lifshitz-Gilbert equation in a mesoscopic samples. This approach [1] combines the necessary nanoscopic accuracy in areas where such precision is required. The normal micromagnetic solving routine of the micromagnum software package [2] has been expanded to include an accurate Heisenberg model in areas with strongly varying spin structures. The model is applied to study for instance the (thermal) stability of skyrmions [3]. [1] A. de Lucia et al., Phys. Rev.
