Abstract

The electronic structure of multiferroic BiFeO{sub 3} has been studied using soft-X-ray emission spectroscopy. The fluorescence spectra exhibit that the valence band is mainly composed of O 2p state hybridized with Fe 3d state. The band gap corresponding to the energy separation between the top of the O 2p valence band and the bottom of the Fe 3d conduction band is 1.3 eV. The soft-X-ray Raman scattering reflects the features due to charge transfer transition from O 2p valence band to Fe 3d conduction band. These findings are similar to the result of electronic structure calculation by density functional theory within the local spin-density approximation that included the effect of Coulomb repulsion between localized d states.

Effect of Mn Substitution for Multiferroic BiFeO3 Probed by High-Resolution Soft-X-Ray Spectroscopy

Journal Article Higuchi, Tohru; Higuchi, T; Hattori, T; ... - Journal of Applied Physics

The electronic structures of BiFeO{sub 3} (BF) and Mn-doped BiFeO{sub 3} (BF(Mn)) have been studied by X-ray absorption spectroscopy (XAS) and soft-X-ray emission spectroscopy (SXES). The BF and BF(Mn) have the mixed valence state of Fe{sup 2+} and Fe{sup 3+}. The valence band is mainly composed of O 2p state hybridized with the majority-spin t{sub 2g} and e{sub g} orbitals of Fe 3d state. The conduction band is composed of the minority-spin t{sub 2g} and e{sub g} orbitals of Fe 3d. The band gaps of BF and BF(Mn) are estimated to be 1.3 eV and 2.7 eV, respectively.

X-ray Spectroscopic Study of the Electronic Structure of CuCrO2

Journal Article Arnold, T; Payne, D; Bourlange, A; ... - Physical Review. B, Condensed Matter and Materials Physics

The electronic structure of the p-type transparent conducting oxide CuCrO{sub 2} has been studied by x-ray photoemission, x-ray absorption, and x-ray emission spectroscopies. The upper part of the valence band derives mainly from Cu?3d and Cr?3d states while the lower valence-band states are of dominant O?2p atomic character, but with pronounced mutual hybridization among Cu?3d, Cr?3d, and O?2p states. Site specific electronic excitations have been studied by resonant inelastic x-ray scattering at the Cu?L and Cr?L edges. Inelastic loss at the Cu?L edge is dominated by on-site interband excitations similar to those found in Cu{sub 2}O, while at the Cr?Lmore »« less

Conduction-band electronic states of YbInCu{sub 4} studied by photoemission and soft x-ray absorption spectroscopies

Journal Article Utsumi, Yuki; Kurihara, Hidenao; Maso, Hiroyuki; ... - Physical Review. B, Condensed Matter and Materials Physics

We have studied conduction-band (CB) electronic states of a typical valence-transition compound YbInCu{sub 4} by means of temperature-dependent hard x-ray photoemission spectroscopy (HX-PES) of the Cu 2p{sub 3/2} and In 3d{sub 5/2} core states taken at h{nu}=5.95 keV, soft x-ray absorption spectroscopy (XAS) of the Cu 2p{sub 3/2} core absorption region around h{nu}{approx}935 eV, and soft x-ray photoemission spectroscopy (SX-PES) of the valence band at the Cu 2p{sub 3/2} absorption edge of h{nu}=933.0 eV. With decreasing temperature below the valence transition at T{sub V}=42 K, we have found that (1) the Cu 2p{sub 3/2} and In 3d{sub 5/2} peaks inmore »« less

Electronic structure of phospho-olivines LixFePO4 (x=0,1) fromsoft-x-ray-absorption and -emission spectroscopies

Journal Article Augustsson, A; Zhuang, G; Butorin, S; ... - Journal of Chemical Physics

The electronic structure of the phospho-olivine LixFePO4 wasstudied using soft-x-ray-absorption (XAS) and emission spectroscopies.Characteristic changes in the valence and conduction bands are observedupon delithation of LiFePO4 into FePO4. In LiFePO4, the Fe-3d states arelocalized with little overlap with the O-2p states. Delithiation ofLiFePO4 gives stronger hybridization between Fe-3d states and O-2p statesleading to delocalization of the O-2p states. The Fe L-edge absorptionspectra yield "fingerprints" of the different valence states of Fe inLiFePO4 and FePO4. Resonant soft-x-ray-emission spectroscopy at the Fe Ledge shows strong contributions from resonant inelastic soft x-rayscattering (RIXS), which is described using an ionic picture of the Fe-3dstates.more »« less

A comparative investigation on structure and multiferroic properties of bismuth ferrite thin films by multielement co-doping

Journal Article Dong, Guohua; Tan, Guoqiang; Luo, Yangyang; ... - Materials Research Bulletin

Highlights: • Multielement (Tb, Cr and Mn) co-doped BiFeO{sub 3} films were fabricated by CSD method. • Multielement co-doping induces a structural transition. • It is found effective to stabilize the valence of Fe ions at +3 by the strategy. • The co-doping at A/B-sites gives rise to the superior multiferroic properties. - Abstract: (Tb, Cr and Mn) multielement co-doped BiFeO{sub 3} (BTFCMO) thin films were prepared by the chemical solution deposition method on fluorine doped tin oxide (FTO) substrates. X-ray diffraction, Rietveld refinement and Raman analyses revealed that a phase transition from rhombohedral to triclinic structure occurs in themore »« less
