ABSTRACT
We have performed a systematic study of the L[sub 2,3] absorption fine structure along the 3d transition metals using X-ray magnetic circular dichroism. This is of importance since the decreased spin–orbit splitting for the early 3d transition metals results in stronger electron core–hole correlations, which lead to dramatic changes in the spectral intensities. For the Fe/V system we demonstrate that the fine structures can be modelled theoretically by means of fully relativistic ab initio calculations that also provide corresponding magnetic moments for vanadium. It turns out that in contrast to the late 3d elements Fe, Co, and Ni, the classical analysis by means of the integral sum rules yields erroneous results for the early 3d transition metals.
