How fast can a magnet switch its orientation, and what are the microscopic mechanisms at play? An HZB team at BESSY II has, for the first time, experimentally assessed the principal microscopic process of ultra-fast magnetism. The methodology developed for this purpose can also be used to investigate interactions between spins and lattice oscillations in graphene, superconductors or other quantum materials.
