I-V curves of Fe/MgO (001) single- and double-barrier tunnel junctions
J. Peralta-Ramos, A. M. Llois, I. Rungger +1
In this work, we calculate with ab initio methods the current-voltage characteristics for ideal single- and double-barrier Fe/MgO (001) magnetic tunnel junctions. The current is ca…
Exploring the limits of the self consistent Born approximation for inelastic electronic transport
William Lee, Stefano Sanvito
The non equilibrium Green function formalism is today the standard computational method for describing elastic transport in molecular devices. This can be extended to include inela…
Magnetism of CoO polymorphs
Thomas Archer, Ruairi Hanafin, Stefano Sanvito
A microscopic explanation for the room temperature ferromagnetism in diluted ZnO:Co is at present rather elusive. Although standard secondary phases can usually be ruled out, it is…
Asymmetric I-V characteristics and magnetoresistance in magnetic point contacts
A. R. Rocha, S. Sanvito
We present a theoretical study of the transport properties of magnetic point contacts under bias. Our calculations are based on the Keldish's non-equilibrium Green's function forma…
