The electronic structure and band hybridization of Co/Ti doped BaFe<sub>12</sub>O<sub>19</sub>
نویسندگان
چکیده
We identify contributions to the valence band of the nanosized BaFe12−2xCoxTixO19 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 identifi ed in the valence band region, at the Ba (5s), Ti (3p) and Co (3p) thresholds, and there are signifi cant contributions to the density of states, residing within 2 eV of the Fermi level, from barium and/or iron.
