We characterize the magnetic domain structure of Co/Pt multilayer fi lms on length scales below one hundred nanometers using resonant magnetic scattering and magnetic force microscopy. The extreme ultraviolet light for the scattering experiment is created by a laser- based high-order harmonic generation source. After illumination with intense ultrashort laser pulses, we observe pronounced changes in the magnetic structure and morphology. Furthermore, this study points out the importance of a detailed analysis of the different laser-induced modifications of a magnetic thin fi lm that influence the scattering patterns.
