I develop and use a novel EUV magneto-optical spectroscopy to capture the microscopic mechanisms underlying ultrafast demagnetization. I also develop an efficient method for spatially-resolved resonant magnetic scattering (RMS) using EUV sources and study the evolution of magnetic textures in an external field. Finally, I will present the results of a time-resolved RMS experiment performed at the Linear Coherent Light Source with soft X-rays. This experiment elucidates the role of spin transport between magnetic domains during laser-driven demagnetization.
