X-ray magnetization movies: Spin dynamics in reality

Gisela Schütz, Max Planck Institute for Intelligent Systems

The field of spintronics and magnonics has become a flourishing synonym of future low-power, ultra-fast and persistent advanced information technologies with fantastic promises. However, the relevant magnetization dynamics with spatial and temporal dimensions in the sub µm and sub ns range are hard to access experimentally. An effective (and maybe the only) magnetic imaging technique elucidating the material-related difficulties and principle limits is provided by time-resolved X-ray microscopy. We explain the physical and technical basics of this method, the potentials and difficulties and discuss several magnetization movies.
