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…
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…
Charge order versus Zener polarons: ferroelectricity in manganites
Dmitry V. Efremov, Jeroen van den Brink, Daniel I. Khomskii
We show that in manganites close to half-doping novel non-bipartite magnetic phases appear due to the interplay between double exchange, superexchange and orbital ordering. In cons…
Orbital effects in manganites
Jeroen van den Brink, Giniyat Khaliullin, Daniel Khomskii
We review some aspects related to orbital degrees of freedom in manganites. The Mn ions in these compounds have double orbital degeneracy and are strong Jahn-Teller ions, ca…
Superstructures at low spin - high spin transitions
D. I. Khomskii, U. Löw
In many transition metal compounds, in particular those containing Fe^{2+} and Co^{3+}, there occur spin-state transitions between low-spin and high-spin (or intermediate-spin) sta…
