SPIN-RESOLVED RESONANT RAMAN-SCATTERING

Spin resolved resonant Raman scattering measurements in Gd metal made by exciting x-ray resonant Raman scattering with circularly polarized x rays near the L(III) edge of Gd are presented. The incident photon e nergy was fixed at the peak of the 2p-->4f quadrupolar transition, and the scattered photon was energy analyzed around the 3d-->2p fluoresce nt energy. Asymmetry ratios in the scattered intensity much larger tha n that of the L(III) XMCD effect (x-ray magnetic circular dichroism) w ere observed upon reversal of the magnetization of the sample or the h elicity of the photon. A detailed comparison of these results with XMC D results from both the M(IV,V) edges and L(III) edge of Gd metal will be discussed. (C) 1996 American Institute of Physics.
