XRMS quantitative study at the L-2 and L-3 edges of Nd in Nd2Fe14B

Room-temperature measurements of the asymmetry ratio of the XRMS signal on a Nd2Fe14B single crystal in the high temperature phase for several Bragg reflections at L-2,L-3 edges of Nd are presented. The experimental results can be qualitatively described by taking into account only the dipolar electronic transitions but the quantitative disagreement suggests that it quadrupolar transition should be introduced into the calculation to achieve a more accurate description of the observed signals.
