Talk: Universität Würzburg, Oberseminar des Lehrstuhls für Mathematik in den Naturwissenschaften,
We consider the numerical approximation of the Landau-Lifshitz-Gilbert equation (LLG), which describes the dynamics of the magnetization in ferromagnetic materials. In addition to the classical micromagnetic contributions, the energy comprises the Dzyaloshinskii-Moriya interaction (DMI), which is the most important ingredient for the enucleation and the stabilization of chiral magnetic skyrmions. Besides convergent tangent plane integrators, the talk also discusses weak-strong uniqueness of solutions as well as a reduced thin-film model, which is particularly interesting for computations.
The talk is based on joint work, in particular, with Giovanni Di Fratta, Michael Innerberger, Carl-Martin Pfeiler, and Michele Ruggeri.
