Observed and calculated energy spectra of Bragg-forbidden reflections in YVO3

Résumé

Resonant x-ray scattering measurements have been performed at the (011) Bragg forbidden reflection of YVO3 at the vanadium K-edge. Data were taken above and below the orbital, magnetic and structural transition occurring at 77 K. Energy spectra calculated by the FDMNES code are shown to be in excellent agreement with our experimental data, conclusively showing the signal to originate from anisotropic tensor of susceptibility scattering; ie. solely due to distortions of the lattice and hence the crystal eld. We thus resolve the ambiguous origin of the resonant energy spectra in the literature.
