Figure 2: Simulations of EMCD in the 3-beam geometry.

(a) Example distribution of the Fe-L₃ edge EMCD signal in the diffraction plane for a beam positioned at to the side from atomic planes. Positions of the transmitted beam disk (red circle) and Bragg scattered beam disks (yellow circles) are marked, as well as the rectangular detector region used in (b) the optimization of the relative EMCD signal strength as a function of convergence angle and sample thickness. (c) Calculated non-magnetic signal as a function of probe position and sample thickness at the Fe-L₃ edge and (d) the corresponding relative EMCD strength. In b,c the convergence semi-angle was set to 10 mrad.
