(a) Scanning transmission X-ray microscope image of a CoPt multilayer containing labyrinthine magnetic domains. (b) Reconstructed Fourier transform hologram of the sample, recorded at the BESSY UE56-SGM beamline. In both cases the difference between opposite helicities of circularly polarized light is shown to reveal the magnetic domains (Eisebitt et al., 2004).
