Hidden multiferroic order in graphene zigzag ribbons
J. Fernández-Rossier
The insulating magnetic phase in graphene zigzag ribbons, predicted both by density functional and mean field Hubbard model calculations, is described without additional approximat…
Anisotropic magnetoresistance in nanocontacts
D. Jacob, J. Fernandez-Rossier, J. J. Palacios
We present ab initio calculations of the evolution of anisotropic magnetoresistance (AMR) in Ni nanocontacts from the ballistic to the tunnel regime. We find an extraordinary enhan…
Magnetism in graphene nano-islands
J. Fernandez-Rossier, J. J. Palacios
We study the magnetic properties of nanometer-sized graphene structures with triangular and hexagonal shapes terminated by zig-zag edges. We discuss how the shape of the island, th…
Electronic Structure of gated graphene and graphene ribbons
J. Fernandez-Rossier, J. J. Palacios, L. Brey
We study the electronic structure of gated graphene sheets. We consider both infinite graphene and finite width ribbons. The effect of Coulomb interactions between the electrically…
Mn-doped II-VI quantum dots: artificial molecular magnets
J. Fernandez-Rossier, Ramon Aguado
The notion of artifical atom relies on the capability to change the number of carriers one by one in semiconductor quantum dots, and the resulting changes in their electronic struc…
Anisotropic magnetoresistance in single electron transport
J. Fernandez-Rossier, R. Aguado, L. Brey
We study the effect of magnetic anisotropy in a single electron transistor with ferromagnetic electrodes and a non-magnetic island. We identify the variation of the chemical p…
