摘要: We demonstrate the feasibility of investigating periodically driven magnetization dynamics in a scanning electron microscope with polarization analysis based on spin-polarized low-energy diffraction. With present setup, analyzing time structure scattering events, we obtain temporal resolution 700 ps, which is demonstrated by means imaging field-driven 100 MHz gyration vortex soft-magnetic FeCoSiB square. Owing to efficient intrinsic timing scheme, high-quality movies, giving two components simultaneously, can be recorded scale hours.
