Magnetic resonance effect in x-ray resonant Raman scattering

Abstract

The magnetic-circular-dichroism spectra of the x-ray resonant Raman scattering associated with the Gd $L{\ensuremath{\alpha}}_{1},$ $L{\ensuremath{\alpha}}_{2},$ and $L{\ensuremath{\beta}}_{2,15}$ fluorescence lines of the ferrimagnetic Gd-Co compound are presented. The incident x-ray energy dependence of these spectra clearly shows not only normal resonance effects, but also magnetic resonance effects between the excited ${2p}_{3/2}$ electron and the $5d$ valence state, i.e., an enhancement of the magnetic effects and the appearance of a structure that corresponds to the magnetic effect of the total fluorescence yield.
