Resonant elastic X-ray scattering: Where from? where to?

Resonant elastic soft x-ray scattering.

Resonant (elastic) soft x-ray scattering (RSXS) offers a unique element, site and valence specific probe to study spatial modulations of charge, spin and orbital degrees of freedom in solids on the nanoscopic length scale. It is not only used to investigate single-crystalline materials. This method also enables one to examine electronic ordering phenomena in thin films and to zoom into electron...

Basics of Resonant Elastic X-ray Scattering theory

We recall the basic equations of Resonant Elastic X-ray Scattering (REXS), starting from the photon-electron Hamiltonian interaction, and describing the different components for the possible transitions. We also make the connection with classical physics and we emphasize the signs of the relevant terms, resonant and non resonant, to comply to the convention on the phase wave.

Magnetic Resonant Inelastic X-ray Scattering

X-ray resonant magnetic scattering from FePd thin films

Depending on the growth conditions, FePd thin films can display a perpendicular magnetic anisotropy associated with chemical order. In competition with the shape anisotropy, this can lead to striped magnetic domains, with moments perpendicular to the film plane. Under these circumstances, magnetic flux closure should occur. The striped domains were studied with soft x-ray resonant magnetic scat...

X-ray resonant exchange scattering from 3d transition metal surfaces

The decay of the elastic X-ray intensity peak versus perpendicular transferred momentum is theoretically studied at energies close to the LII edge, for single crystal Fe surfaces and thin Fe films. For the single crystal surface, large intensity changes are observed upon reversal of the direction of the magnetisation. For thin Fe films, which are known to exhibit perpendicular magnetisation, an...
