MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Low energy domain patterns in soft ferromagnetic films

Antonio DeSimone, Robert V. Kohn, Stefan Müller, Felix Otto and Rudolf Schäfer

Abstract

Computations based on a two-dimensional model recently proposed by the authors shed some new light on classical experimental observations of permalloy films under in-plane applied magnetic fields. Some quantities, such as the magnetic charge density or the magnetization in the regions of the film where the external field penetrates the sample are easily and robustly computable through energy minimization and are much less prone to hysteresis than the underlying domain structures.
