Orbital-assisted metal-insulator transition in VO
M. W. Haverkort, Z. Hu, A. Tanaka +9
We found direct experimental evidence for an orbital switching in the V 3d states across the metal-insulator transition in VO. We have used soft-x-ray absorption spectroscopy…
Characterization of Magnetic Components in the Diluted Magnetic Semiconductor ZnCoO by X-ray Magnetic Circular Dichroism
M. Kobayashi, Y. Ishida, J. l. Hwang +12
We report on the results of x-ray absorption (XAS), x-ray magnetic circular dichroism (XMCD), and photoemission experiments on {\it n}-type ZnCoO () thin film,…
Controlling orbital moment and spin orientation in CoO layers by strain
S. I. Csiszar, M. W. Haverkort, Z. Hu +6
We have observed that CoO films grown on different substrates show dramatic differences in their magnetic properties. Using polarization dependent x-ray absorption spectroscopy at…
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…
Soft X-ray magnetic circular dichroism study of the ferromagnetic CrTe
K. Yaji, A. Kimura, C. Hirai +8
The 2p core excited XAS and XMCD spectra of CrTe with several concentrations of =0.11-0.33 have been measured. The observed XMCD lineshapes are found to very weakly depe…
