Magnetic Phenomena span many orders of magnitude in time, with the fastest processes ranging into the pico- and femtosecond regime. At the same time, the investigation of increasingly smaller structures in the nanometer regime is of interest – driven both by technological applications and fundamental science questions. To make progress in these areas it is thus very valuable to be able to observe magnetic structure with high spatial and temporal resolution.
Scattering and holographic imaging experiments with x-rays give unique insight in nanomagnetic dynamics. I will give an overview how such experiments are performed in different temporal regimes at synchrotron and free electron laser sources and discuss recent results in this field.
