Fig. 33: Calculated spectra for the M5 edge (3d5/2 -> 4f) edge of Dy3+ (4f 9). Left panel: absorption spectrum, right panel: fluorescence yield spectrum. The solid lines show the spectra for incoming unpolarised photons. The curves labelled q = +1, q = -1 are for the two opposite directions of circular polarisation, with photon wavevector parallel to the direction of magnetisation. The curve labelled q = 0 is for linear polarisation parallel to the direction of magnetisation.
