Predicting Magnetization Pattern

1:30 PM-2:15 PM
Room: Liberty B&C
Chair: Stefan Müller, Max-Planck Institute for Mathematics in the Sciences, Germany

The magnetization of ferromagnetic materials forms complex structures of different dimensionality and on a broad range of length scales: domains, walls of different internal structure, Bloch lines and vortices.

Predicting the formation of these structures, and understanding their interaction and overall effects is crucial for key technological applications.

The rich source of experimental data and the simple mathematical form of the well-accepted model makes this analysis a good model problem to develop new mathematical tools for multiscale problems in material science.

The speaker will report on the rigorous derivation of new dimensionally reduced theories for thin films, their numerical simulation and experimental validation.
