Paramagnon dispersion in beta-FeSe observed by Fe L-edge resonant inelastic x-ray scattering
- Abstract:
- We report an Fe L-edge resonant inelastic x-ray scattering (RIXS) study of the unusual superconductor βFeSe. The high-energy resolution of this RIXS experiment (≈55 meV FWHM) made it possible to resolve low-energy excitations of the Fe 3d manifold. These include a broad peak which shows dispersive trends between 100 and 200 meV along the (π, 0) and (π,π) directions of the one-Fe square reciprocal lattice, and which can be attributed to paramagnon excitations. The multiband valence state of FeSe is among the most metallic in which such excitations have been discerned by soft x-ray RIXS.
