Title: Charge-transfer and Mott-Hubbard Excitations in FeBo{sub 3} : Fe K-edge resonant Inelastic x-ray scattering study.

Abstract

Momentum-resolved resonant inelastic x-ray scattering (RIXS) spectroscopy has been carried out successfully at the Fe K-edge for the first time. The RIXS spectra of a FeBO{sub 3} single crystal reveal a wealth of information on {approx} 1-10 eV electronic excitations. The IXS signal resonates when the incident photon energy approaches the pre-edge (1s{sup -}-3d) and the main-edge (1s{sup -}-4p) of the Fe K-edge absorption spectrum. The RIXS spectra measured at the pre-edge and the main-edge show quantitatively different dependences on the incident photon energy, momentum transfer, photon polarization, and temperature. We present a multielectron analysis of the Mott-Hubbard (MH) and charge transfer (CT) excitations, and calculate their energies. Electronic excitations observed in the pre-edge and main-edge RIXS spectra are interpreted as MH and CT excitations, respectively. We propose the electronic structure around the chemical potential in FeBO{sub 3} based on the experimental data.
