Figure 4
(Colour online) A poorly lithographed sample is used. (a, b and c) Several raster maps with diffraction contrast corresponding to Fe3O4, Pt and Co, respectively; the colour of the frame corresponds to the position on the radial scan (d) indicated by the corresponding arrow (see text for more details). (d) Radial scan in the vicinity of the Bragg peaks characteristic of the different layers performed with a point detector in a monochromatic (7 keV) focused X-ray beam, at different lateral positions on the sample (see inset legend). Positions in the reciprocal space (angular values) at which raster maps (a) to (c) were performed are marked by coloured arrows.  [article HTML]
