(a) Holography mask (1 µm Au) with a 2.4 µm square aperture, two point-references, and a slit, placed on top of the 50 nm thick Co91Tb9 sample. (b) Scattering pattern collected at 778 eV (Co L3 resonance) using a photon beam with right circular polarization and L = +1. Arrows associate different scattering features with sample and mask characteristics. (c) Image of the perpendicular magnetic domains obtained by taking the difference between left- and right-circular polarization measurements. (d) MFM image of the same sample acquired in a different region of the surface. (e–g) FTH images of magnetic domains in the Co91Tb9 sample obtained at the Tb 4d–4f resonance [(e), L = −1] and at the Co 2p–3d resonance [(f), L = −1, and (g), L = +1]. Diamonds indicate the size of the object aperture. The imaged sample area differs between (c) and (e–g).
