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 energy was fixed at the peak of the 2p-->4f quadrupolar transition, and the scattered photon was energy analyzed around the 3d-->2p fluorescent energy. Asymmetry ratios in the scattered intensity much larger than that of the L(III) XMCD effect (x-ray magnetic circular dichroism) were observed upon reversal of the magnetization of the sample or the helicity of the photon. A detailed comparison of these results with XMCD results from both the M(IV,V) edges and L(III) edge of Gd metal will be discussed. (C) 1996 American Institute of Physics.
