(2007) Dipolar excitations at the L3 x-ray absorption edges of the heavy rare earth metals. Physical Review Letters, 99 (24). -247401 . ISSN 1079-7114. (Full text available)
We report measured dipolar asymmetry ratios at the LIII edges of the heavy rare earth metals. The results are compared with a first principles calculation and excellent agreement is found. A simple model of the scattering is developed, enabling us to re-interpret the resonant x-ray scattering in these materials and to identify the peaks in the asymmetry ratios with features in the spin and orbital moment densities.
