Observation of interband transitions in polarized electron energy loss spectra of Gd(0001)

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We have detected the 4f 7(5d6s)3→4f 8(5d6s)2 interband transition in an angular-resolved, inelastic scattering experiment with spin-polarized, low-energy electrons from ferromagnetic Gd(0001). The spectrum of the inelastic scattering asymmetry clearly reveals the dominant spin-dependent energy loss mechanism involved. Furthermore its comparison with elastic scattering data allows a characterization of the combined role of diffraction and energy loss processes in inelastic electron scattering.

  13. In electron atom scattering experiments [14] spin conservation of incident and scattered electrons is implied, leading to a symmetric radial wave function for antiparallel spin orientation (singlet state) and to an antisymmetric wave function in the electron coordinates for parallel spin orientation (triplet state). For a symmetric interaction potential of the Coulomb type the matrix element for the triplet scattering contribution vanishes
