Figure 1. Angular dependent magnetic transmission X-ray microscopy configuration.

(a) Experimental transmission X-ray microscopy measurement geometry and sketch of the magnetization configuration in a parallel stripe pattern; alternate stripes, denoted as 1 and 2 and shown in red and blue colours, respectively, have opposite M_z components but the same M_x, as indicated by the red and blue arrows, that correspond to the magnetization direction in each stripe; θ is the angle between the incoming photon beam (indicated by a green arrow and having hν energy) and the sample surface normal direction (vertical dotted lines denoted as n); φ is the angle between domain 1 magnetization and n direction; sample rotation axis (dashed–dotted line, denoted as r, parallel to the y axis and contained in the sample surface plane) allows to vary θ. (b) Calculated contrast curves C(θ, φ) versus X-ray beam orientation (θ) for different domain configurations (φ values). For φ≠0, the maxima become displaced to positive or negative values depending on the sign of φ.
