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…
Spin and orbital degrees of freedom in transition metal oxides and oxide thin films studied by soft x-ray absorption spectroscopy
M. W. Haverkort
The class of transition metal compounds shows an enormous richness of physical properties, such as metal-insulator transitions, colossal magneto-resistance, super-conductivity, mag…
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…
Nature of magnetism in CaCoO
Hua Wu, M. W. Haverkort, Z. Hu +2
We find using LSDA+U band structure calculations that the novel one-dimensional cobaltate CaCoO is not a ferromagnetic half-metal but a Mott insulator. Both the octahed…
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…
Magnetic versus crystal field linear dichroism in NiO thin films
M. W. Haverkort, S. I. Csiszar, Z. Hu +7
We have detected strong dichroism in the Ni x-ray absorption spectra of monolayer NiO films. The dichroic signal appears to be very similar to the magnetic linear dichroi…
