Strength of Correlations in a Silver Based Cuprate Analogue
Riccardo Piombo, Daniel Jezierski, Henrique Perin Martins +10
AgF2 has been proposed as a cuprate analogue which requires strong correlation and marked covalence. On the other hand, fluorides are usually quite ionic and 4d transition metals t…
Compensation temperatures and exchange bias in La1.5Ca0.5CoIrO6
L. T. Coutrim, E. M. Bittar, F. Stavale +8
We report on the study of magnetic properties of the La1.5Ca0.5CoIrO6 double perovskite. Via ac magnetic susceptibility we have observed evidence of weak ferromagnetism and reentra…
Importance of the V 3d-O 2p hybridization in the Mott-Hubbard material V2O3
R. J. O. Mossanek, M. Abbate
We studied the changes in the electronic structure of V2O3 using a cluster model. The calculations included fluctuations from the coherent band in the metallic phase, and non-local…
Cluster model calculations with non-local screening channels of metallic and insulating VO2
R. J. O. Mossanek, M. Abbate
We studied the changes in the electronic structure of VO2 across the metal-insulator transition. The main technique was cluster model calculations with non-local screening channels…
Optical response of metallic and insulating VO2 calculated with the LDA approach
R. J. O. Mossanek, M. Abbate
We calculated the optical response of metallic and insulating VO2 using the LDA approach. The band structure calculation was based in the full-potential linear-muffin-tin method. T…
Non-local coherent screening in the bandwidth controlled Ca1-xSrxVO3 series
R. J. O. Mossanek, M. Abbate, A. Fujimori
We studied the electronic structure of the Ca1-xSrxVO3 series using a cluster model. Both the coherent and incoherent structures in photoemission correspond to well screened states…
