Summary

This summer school provides expert knowledge on theory, experiments and possible applications of chiral magnetism. Timely research topics, considering e.g. chiral domain walls, spin spiral and cycloids, skyrmions, magnonic crystal properties and directional dichroism of microwaves are covered.

Content

The school will address experimental and theoretical physics, experimental and computational material science, microengineering and electrical engineering. The summer school will offer the students chances to communicate with researchers from both academic and industry for further career plan.
