Magnetic configurations with chiral properties have attracted enormous interest after the discovery of the magnetic skyrmions lattice in non-centrosymmetric bulk crystals. The asymmetric exchange interaction, Dzylonshinskii-Moriya interaction (DMI) that cooperates with symmetric exchange interaction, dipolar and Zeeman interactions, allows for further non-collinear spin structures beyond skyrmions, such as e.g. spin helices, conical states, and spin cycloids. The field becomes even richer after the realization of individual skyrmions in multilayers with broken inversion symmetry and skyrmions lattices in polar magnets. Chirality is the key to make different configurations distinguishable and promotes topological protections. Thereby chiral magnetic configurations are promising for next-generation data storage devices, and nanoscale magnonic logic. They allow for low-power consumption and improved stability.
This summer school will provide a broad and in-depth view on chiral magnetism and timely research topics to students, considering e.g. chiral domain walls, spin spiral and spin cycloids, skyrmions, magnonic crystal properties and directional dichroism of microwaves. The school will address experimental and theoretical physics, experimental and computational material science, microengineering and electrical engineering.
