Abstract

We report on the magnetic circular dichroism of nonresonant x-ray Raman scattering. The circular dichroism has been observed at the ${L}_{\mathrm{II},\mathrm{III}}$ edges on a pure iron sample. The observed magnetic effect is $\ensuremath{\sim}2%$. The dichroism spectra exhibit a significant dependence on the direction of the magnetization vector. We have constructed an effective theory to understand these behaviors. The dichroism arises from the orbital scattering and the spin scattering having different angular dependences. The calculation reproduces well the observed spectra.
