We propose to directly measure the ultrafast spatial evolution of laser-excited spin and charge densities inside magnetic multilayer samples employing ultrafast XUV and soft X-ray magnetic reflectivity experiments at HHG and XFEL sources. Using the coherence properties of the ultra-short FEL pulses we also aim at measuring the temporal fluctuations of spin and charge densities by means of resonant magnetic X-ray photon correlation spectroscopy. Both information, the temporal evolution of the spin and charge densities and their respective fluctuations will help to unravel the microscopic details of processes involved in ultrafast magnetization dynamics.
