We are very pleased with these results, which show clear images of magnetic domains in a Co/Pt multilayer thin film with perpendicular magnetic anisotropy. We achieved a spatial resolution of ∼30 nm, and this was only limited by the sample period. By adjusting the experimental setup we hope to achieve 15 nm in the near future.

The object and reference slit are illuminated by the coherent x-ray beam. (b) The hologram formed by the interference of the scattered x-rays from the object and reference slit is recorded on the CCD camera in the far field. (c) A linear differential filter, defined by the derivative of the slit direction, is multiplied by the hologram before performing a Fourier transform to retrieve the reconstructed image.
