Abstract

We present a method for high-resolution magnetic imaging at linearly polarized partially coherent x-ray sources. The magnetic imaging was realized via Fourier transform holography. In order to achieve elliptical x-ray polarization, three different filters were designed based on the x-ray magnetic circular dichroism effect. We present proof-of-principle images of magnetic nanostructures and discuss the application of the method for future experiments at free-electron laser sources.

Fig. 1.
Fig. 1. (a) Schematic of the beamline setup. The linearly polarized light was elliptically polarized by either polarizing unit A, unit B, or unit C and then incident on the samplemask structure. The hologram was recorded with a CCD camera. (b) For polarizer B a sliced electromagnet was used in order to saturate the magnetic film in the out-of-plane direction. (c) Polarizer C was magnetized in the in-plane direction by two permanent magnets. (d) The holography mask was processed into the gold film (yellow) on a Si3N4 membrane (gray) held by a silicon frame (blue). The magnetic film sample (magenta) was deposited on the opposite membrane side.

Fig. 2. The theoretically calculated transmission rates T ± (thin green lines) using Eq. (1), the mean transmission T = (T + + T −)/2 (thick green line), degree of polarization P (red), and figure of merit 10 × TP 2 (blue) in dependence on the number of multilayer repeats for the multilayer system used for polarizers A (a), and B (b), respectively. Analogous plots for a pure Co layer (polarizer C) (c) in dependence on the layer thickness (fixed incidence angle 45°) and (d) in dependence on the incidence angle (fixed layer thickness 40nm). Calculations are made for λ at the Co L3-edge. The arrows point to the design properties of the particular polarizer.

Fig. 3. Magnetic hysteresis loops of polarizers A (a), and B (b). The out-of-plane film magnetization M normalized to the magnetization in saturation M s is shown in dependence on the external magnetic field H applied in the out-of-plane direction. Polarizer A features full remanence and can be used without any external magnetic field, whereas for Polarizer B an electromagnet is needed. The arrows point to the external fields used in the imaging experiment.

Fig. 4. Images of the magnetic domain pattern of the first (a), (b) and second sample (c), (d) achieved via FTH imaging and taken with either circularly polarized light from an undulator or linearly polarized x-rays passing through a polarizer. The FOV diameter is 1.5µm in both cases. The yellow boxes in panel (c) mark the pillar position of the second sample’s prepatterned substrate.

Fig. 5. Labyrinth domains of the third sample imaged in a 0.8µm FOV via FTH with and without polarizer. Panels (a) and (d) show the image results by Fourier-transforming the difference of the holograms taken with opposite helicity. Additionally, successful image reconstruction was also achieved solely from the holograms taken with positive (b), (e) or negative (c), (f) helicity.
