Spin State Transition in LaCoO3 Studied Using Soft X-ray Absorption Spectroscopy and Magnetic Circular Dichroism
Maurits W. Haverkort,Zhiwei Hu,Julio C. Cezar,T. Burnus,H. Hartmann,M. Reuther,C. Zobel,Thomas Lorenz,Arata Tanaka,N. B. Brookes,H. H. Hsieh,Hong-Ji Lin,C. T. Chen,Liu Hao Tjeng +13 more
TL;DR: Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co-L(2,3) edge, the spin state transition in LaCoO3 can be well described by a low-spin ground state and a triply degenerate high-spin first excited state as mentioned in this paper.

T. Song,G. L. Sun,Chengtian Lin,G. M. De Luca,Marco Salluzzo,Giniyat Khaliullin,T. Schmitt,Lucio Braicovich,Bernhard Keimer +20 more
TL;DR: In this article, the case for magnetically mediated superconductivity was strengthened by the discovery of high-energy magnetic excitations that are not affected by chemical doping levels within several cuprates.
Journal ArticleDOI
Orbital-Assisted Metal-Insulator Transition in VO2
Maurits W. Haverkort,Zhiwei Hu,Arata Tanaka,W. Reichelt,Sergey V. Streltsov,M. A. Korotin,V. I. Anisimov,H. H. Hsieh,Hong-Ji Lin,C. T. Chen,D. I. Khomskii,Liu Hao Tjeng +11 more
TL;DR: These results strongly suggest that, in going from the metallic to the insulating state, the orbital occupation changes in a manner that charge fluctuations and effective bandwidths are reduced, that the system becomes more one dimensional and more susceptible to a Peierls-like transition.
Journal ArticleDOI
Multiplet ligand-field theory using Wannier orbitals
TL;DR: In this article, the authors demonstrate how ab initio cluster calculations including the full Coulomb vertex can be done in the basis of localized Wannier orbitals which describe the low-energy density functional (local-density approximation) band structure of an infinite crystal, e.g., the transition-metal $3d$ and oxygen $2p$ orbitals.
