X-RAY RESONANT RAMAN-SCATTERING FROM GD3FE5O12

The Fe 3p(3/2,1/2) --> Is X-ray Resonant Raman Scattering (RRS) from G d3Fe5O12 shows an intense resonating feature in the vicinity of the K absorption edge and a pronounced satellite in the emission spectrum ab ove threshold. Comparison with Gd 3d(5/2) --> 2p(3/2) RRS reveals comm on characteristics. The results are explained by inclusion of quadrupo lar (E2) excitations in the intermediate states and electron correlati on effects in the final states of the inelastic scattering process. Ex perimental aspects on how inelastic scattering spectra are recorded ar e briefly discussed. (C) 1997 Elsevier Science B.V.
