A different look at the spin state of Co $^{3 +}$ ions in CoO $_{5}$ pyramidal coordination

Z. Hu, Hua Wu, M. W. Haverkort +10

Using soft-x-ray absorption spectroscopy at the Co- $L_{2, 3}$ and O- $K$ edges, we demonstrate that the Co $^{3 +}$ ions with the CoO $_{5}$ pyramidal coordination in the layered Sr $_{2}$ …

A New Scenario on the Metal-Insulator Transition in VO2

Arata Tanaka

The metal-insulator transition in VO2 was investigated using the three-band Hubbard model, in which the degeneracy of the 3d orbitals, the on-site Coulomb and exchange interactions…

Soft X-ray magnetic circular dichroism study of the ferromagnetic Cr $_{1 - δ}$ Te

K. Yaji, A. Kimura, C. Hirai +8

The 2p core excited XAS and XMCD spectra of Cr $_{1 - δ}$ Te with several concentrations of $δ$ =0.11-0.33 have been measured. The observed XMCD lineshapes are found to very weakly depe…
