Possibility for an intermediate-spin ground state in the charge-transfer material SrCoO3

Autor: Potze, R. H., Sawatzky, G. A., Abbate, M.

Publikováno v: Physical Review B, 51(17), 11501-11506. AMER PHYSICAL SOC

We discuss the possibility of an intermediate-spin ground state for a d5 (d6) system. The intermediate-spin state is stabilized by the relative stability of the ligand hole state that it hybridizes with. Using atomic multiplet calculations we showed

THE ELECTRONIC-STRUCTURE OF TI4O7 STUDIED BY RESONANT PHOTOEMISSION

Autor: ABBATE, M, POTZE, R, SAWATZKY, GA, SCHLENKER, C, TEEHAN, D, TURNER, TS

Publikováno v: Solid State Communications, 94(6), 465-469. PERGAMON-ELSEVIER SCIENCE LTD

We present and discuss resonant photoemission (PES) spectra of Ti4O7 taken at 50 and 300 K. The PES spectra taken in the metallic phase at 300 K show Ti 3d bands at the Fermi level and O 2p bands at higher binding energies. The intensity of the Ti 3d

BAND-STRUCTURE AND CLUSTER-MODEL CALCULATIONS OF LACOO(3) IN THE LOW-SPIN PHASE

Autor: ABBATE, M, POTZE, R, SAWATZKY, GA, FUJIMORI, A

Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 49(11), 7210-7218. AMER PHYSICAL SOC

We present band-structure and cluster-model calCulatiOns Of LaCoO3 in the low-spin phase. The purpose of these calculations is to contrast and complement the results and conclusions of recent spectroscopic studies. The total density of states (DOS) i

ELECTRONIC-STRUCTURE AND SPIN-STATE TRANSITION OF LACOO3

Autor: ABBATE, M, FUGGLE, JC, FUJIMORI, A, TJENG, LH, CHEN, CT, POTZE, R, SAWATZKY, GA, EISAKI, H, UCHIDA, S

Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 47(24), 16124-16130. AMER PHYSICAL SOC

We present soft-x-ray absorption spectra (XAS) of LaCoO3 taken at different temperatures (80-630 K). The shape of the multiplets in the Co 2p XAS spectra conveys information on the symmetry and spin of the ground state. The 0 Is XAS spectra are relat

Band-theory description of high-energy spectroscopy and the electronic structure of LiCoO2

Autor: Czyzyk, M.T., Potze, R., Sawatzky, GA

Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 46(7), 3729-3735. AMER PHYSICAL SOC

LiCoO2 can be viewed as the end member of the Li-doped LixCo1-xO2 system. It was suggested that this system exhibits a transition from high-spin Co ions in CoO to low-spin Co ions in LiCoO2. We present a systematic study of the electronic properties

PRASEODYMIUM 3D-CORE AND 4D-CORE PHOTOEMISSION SPECTRA OF PR2O3

Autor: OGASAWARA, H, KOTANI, A, POTZE, R, SAWATZKY, GA, THOLE, BT

Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 44(11), 5465-5469. AMER PHYSICAL SOC

Experimental data and theoretical calculations are shown for Pr 3d and 4d x-ray photoemission spectra (XPS) of Pr2O3. The observed spectral structures are well explained by the theoretical results that are obtained with the impurity Anderson model by
