Magnetic materials with dimensions of a few tens of nanometers are important for the development of ultrahigh-density magnetic storage and sensor devices. Magnetic microstructure largely determines functionality, and imaging of magnetic domains and magnetization reversal behavior is an outstanding challenge. Magnetic X-ray microscopy makes it possible to investigate magnetization phenomena with elemental specificity and high spatial and temporal resolution.
