Charge disproportionation and nano phase separation in SrNiO
H. Guo, Z. W. Li, C. F. Chang +16
We have successfully grown centimeter-sized layered SrNiO single crystals under high oxygen pressures of 120 bar by the floating zone technique. This enabled us to perform n…
The -axis dimer and its electronic break-up: the insulator-to-metal transition in TiO
C. F. Chang, T. C. Koethe, Z. Hu +17
We report on our investigation of the electronic structure of TiO using (hard) x-ray photoelectron and soft x-ray absorption spectroscopy. From the distinct satellite struc…
The spin state transition in LaCoO; revising a revision
M. W. Haverkort, Z. Hu, J. C. Cezar +11
Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co- edge we reveal that the spin state transition in LaCoO can be well described by a…
Spectroscopy of stripe order in La1.8Sr0.2NiO4 using resonant soft x-ray diffraction
C. Schuessler-Langeheine, J. Schlappa, A. Tanaka +13
Strong resonant enhancements of the charge-order and spin-order superstructure-diffraction intensities in La1.8Sr0.2NiO4 are observed when x-ray energies in the vicinity of the Ni…
Determination of the orbital moment and crystal field splitting in LaTiO
M. W. Haverkort, Z. Hu, A. Tanaka +18
Utilizing a sum-rule in a spin-resolved photoelectron spectroscopic experiment with circularly polarized light, we show that the orbital moment in LaTiO is strongly reduced bot…
A different look at the spin state of Co ions in CoO pyramidal coordination
Z. Hu, Hua Wu, M. W. Haverkort +10
Using soft-x-ray absorption spectroscopy at the Co- and O- edges, we demonstrate that the Co ions with the CoO pyramidal coordination in the layered Sr…
