(color online) Simulated dynamical coefficients of YIG. (a) Crystal structure of YIG along the [1-10] direction. (b) Simulated thickness dependent EMCD signals under (444) two-beam case. (c) and (d) Simulated EMCD signals with (4-44) planes strongly excited under two-beam and three-beam case. (e) Simulated EMCD signals with (8-88) planes strongly excited. The circles represent the detector positions with strong intensity of EMCD signals for high SNR (from Ref. [26], Figs. 1 and 2).
