Magnetization dynamics and chirality control in the Cu₂OSeO₃ skyrmion compound — •Rolf Versteeg, Matteo Montagnese, and Paul Van Loosdrecht — II. Physikalisches Institut, Universität zu Köln, Zülpicher Straße 77

Skyrmions are 2D-topologically protected magnetic structures which appear as screw-like nanostructures. The combination of different magnetic interactions gives rise to these intriguing structures with sizes generally between 20-90nm. Skyrmions promise to be of great technological value in the form of nano-sized, easily writeable and readable bits. Apart from the technological interest these magnetic structures also open new avenues in fundamental research in light-matter interaction, magnetization dynamics and chirality. Our ideas and recent efforts to study Skyrmion dynamics and their formation in the multiferroic insulator Cu₂OSeO₃ by means of different optical techniques will be presented.
