Magnetization reversal dynamics at nanosecond timescales is an important subject for many technological applications of magnetic materials. Furthermore, time-resolved magnetic microscopy measurements using the magneto-optical Kerr effect have demonstrated the importance of exploring spatially non-uniform magnetization dynamics by microscopic techniques. Up to now, these experiments have been performed on thin film structures consisting of only one single magnetic layer. Many of the most exciting phenomena in recent magnetism research, however, occur in layered systems consisting of several interacting ultrathin magnetic layers.

   Magnetic domain imaging by photoelectron emission microscopy can be extended to obtain time and layer resolved magnetic domain images of dynamic processes in multilayered magnetic samples. This is achieved by synchronizing short magnetic field pulses that are applied to the sample to the time structure of the synchrotron radiation (50 ps pulses every 800 ns at BESSY single bunch mode of operation).
