Domain walls in nanostructures can be compact micromagnetic objects that can be moved using magnetic field or spin polarized current pulses. We want to obtain a better understanding of the dynamics of magnetic domain walls and its connection to magnetic damping mechanisms.

For this purpose we investigate the complex domain wall motion in nano- and microstripes as well as in nanotubes with high spatial resolution time resolved techniques. In order to interpret the experimental results, we compare them to micromagnetic simulations performed using GPU based micromagnetic codes.
