Description
The spin-dependent absorption of circularly polarized x rays at the L3 edge of Er has been studied in Er2Fe14B. Two distinct contributions, above and below the Fermi energy, are present. While they have been ascribed to dipolar and quadrupolar transitions to the empty 5d and 4f states, respectively, we find that the angular dependence of both features was well described as dipolar. The results are compared to a theoretical spectrum for Er metal
