Combining X‐ray magnetic circular dichroism (X‐MCD) with a transmission X‐ray microscope (TXM) allows to image element‐specifically magnetic domain structures with 25 nm lateral resolution. Both in‐plane and out‐of‐plane systems can be studied in applied magnetic fields. Thus field‐dependent parameters, as individual nucleation fields in magnetic nanostructures can be deduced and related to morphology. Images of thermomagnetically written bits in magneto‐optical TbFeCo media proof the reliability of the writing process and the importance of an exact thermal design of the systems. Domains observed at corresponding Co L edges proof the chemical sensitivity of M‐TXM and its potential to image few monolayer systems.
