The anomalous lineshape at L edge resonances of Nd/Pr superlattices

X-ray magnetic resonant scattering studies of Nd/Pr superlattices have allowed the magnetic ordering in both contstituents of the superlattice to be studied seperately. However, the resonances at the L edges were found to be anomalous, and the aim of this experiment was to understand the lineshape of these energy dependencies. The dominant features, a large peak at the absorption edge and a high-energy shoulder, were found to be due to a dipolar transition to a broad 5d band
