Effect of N interstitial complexes on the electronic properties of GaAsN alloys from first principles
J. D. Querales-Flores, C. I. Ventura, J. D. Fuhr
Several approaches have been used to investigate the impact of Nitrogen (N) on the electronic structure of GaAsN alloys, however, there is no agreement between theory…
Phase diagram description of the CaCuFeO double perovskite
Ivon R. Buitrago, C. I. Ventura, R. Allub
CaCuFeO exhibits a temperature-induced transition from a ferrimagnetic-insulating phase, in which Fe appears charge disproportionated, as Fe and Fe, to…
The two gap transitions in GeSn: effect of non-substitutional complex defects
J. D. Querales-Flores, C. I. Ventura, J. D. Fuhr +1
The existence of non-substitutional -Sn defects in GeSn was confirmed by emission channeling experiments [Decoster et al., Phys. Rev. B 81, 155204 (2010)], which e…
Normal state magnetotransport properties of -FeSe superconductors
J. D. Querales-Flores, M. L. Amigó, G. Nieva +1
We present -FeSe magnetotransport data, and describe them theoretically. Using a simplified microscopic model with two correlated effective orbitals, we determined the normal st…
Normal state electronic properties of LaOFBiS superconductors
J. D. Querales Flores, C. I. Ventura, R. Citro +1
A good description of the electronic structure of BiS-based superconductors is essential to understand their phase diagram, normal state and superconducting properties. To de…
Magnetic excitations of perovskite rare-earth nickelates: RNiO
Ivon R. Buitrago, Cecilia I. Ventura
The perovskite nickelates RNiO (R: rare-earth) have been studied as potential multiferroic compounds. A certain degree of charge disproportionation in the Ni ions has been conf…
