The developments of ultrafast lasers technology and techniques triggered significant progress in the field of nonlinear optics. In particular, the high-harmonic generation sources (HHG) provide nowadays spectrally broadband light pulses that can sustain ultrashort laser pulses with pulse durations down to attoseconds timescale. As the photon energies cover the VUV range (up to 100 eV and beyond) such HHG light sources can be used as complementary tools to study, for instance, element-specific dynamics with improved time resolution. Recently the feasibility of the time-resolved setups employing HHG sources to investigate magnetization dynamics [using magneto-optical Kerr effect (MOKE) for probing] has been explored. For selected magnetic model systems we plan to use the VUV-MOKE as a complementary tool to our ultrafast magnetization dynamics studies done in the soft X-ray range.
