Ultrafast and very Small: Discover Nanoscale Magnetism With picosecond time resolution using X-Rays

Dr. Hendrik Ohldag, SLAC National Accelerator Laboratory, CA, USA

The goal of this talk is to present an introduction to the field of synchrotron based soft x-ray microscopy, which is becoming a tool available at every synchrotron. Particular focus will be given to time resolved measurements by employing the pulsed nature of the synchrotron source providing x-ray flashes with 50 ps duration. The general introduction will be followed by a set of examples, that includes the visualization of spin injection from non-magnet into ferromagnets, spin wave modes in ferromagnetic resonance of structured samples and spin waves excited by spin-torque nano-oscillators.
