The feasibility of using light to manipulate and control the magnetic order on ultrafast time scales has opened a vast field of research focussed on magnetization dynamics. This research is driven by the ever increasing demands for faster speeds of writing and retrieving the magnetically stored information as well as by the fundamental scientific interest regarding the involved microscopic processes. Among the fascinating and in the same time highly challenging issues under investigation I mention the ultrafast demagnetization dynamics [1,2], the photoinduced generation of magnetization  as well as all-optical magnetization switching . In this contribution, I will present our recent studies addressing these issues using time-resolved magneto-optics in the visible and X-ray spectral range.
