HERFD XAS, XES and RIXS study to reveal the electronic structure of single atom doped TiO2 nanocrystals

We propose to investigate the role of orbital hybridization in the magnetism of TiO2 and single-atom doped (e.g. Fe, Co, Ni, and Cu) TiO2 nanocrystals using element selective HERFD XAS, XES, and resonant inelastic x-ray scattering (RIXS). The motivation of this work is to find the reason behind the ferromagnetism in the single-atom (e.g. Fe, Co, Ni, and Cu) doped TiO2, an unexpected property with no bulk analogue. These XES/RIXS measurements can uniquely determine whether the observed magnetization is due to a magnetic moment from one of the constituent elements, or their orbital hybridization.
