The electronic structure and band hybridization of Co/Ti doped BaFe12O19

Abstract We identify contributions to the valence band of the nanosized BaFe 12−2 x Co x Ti x O 19 barium ferrite particles, from the cobalt and titanium dopants. Resonant photoemission results show that cobalt and titanium dopants strongly hybridize with the barium ferrite matrix. Fano resonances are identified in the valence band region, at the Ba (5s), Ti (3p) and Co (3p) thresholds, and there are significant contributions to the density of states, residing within 2 eV of the Fermi level, from barium and/or iron.
