Investigation of Gd compounds using synchrotron radiation

The electronic structure of ferromagnetic compound GdTiGe has been investigated using element sensitive methods-X-ray absorption spectroscopy (XAS), X-ray magnetic circular dichroism (XMCD) and resonant inelastic X-ray scattering (RIXS). Additionally, another ferromagnet GdTiSi has been studied using XMCD. XMCD revealed a strong dichroic signal, at Gd L-2 and L-3 edges, which can be related to polarisation of Gd 5d band. XAS at Ti L-2,L-3 edges has exhibited a structure which appeared to be in general agreement with the LAPW calculations. RIXS spectra have shown some resonance features for photon energies close to Ti L-2 and Gd M-5 edges. (c) 2005 Elsevier B.V. All rights reserved.
