Electron gas at the interface between two antiferromagnetic insulating manganites
M. J. Calderon, J. Salafranca, L. Brey
We study theoretically the magnetic and electric properties of the interface between two antiferromagnetic and insulating manganites: La0.5Ca0.5MnO3, a strong correlated insulator,…
MagnetoResistance of graphene-based spin valves
L. Brey, H. A. Fertig
We study the magnetoresistance of spin-valve devices using graphene as a non-magnetic material to connect ferromagnetic leads. As a preliminary step we first study the conductivity…
Magnetoresistance in an all-manganite heterostructure
J. Salafranca, M. J. Calderon, L. Brey
We study the magnetic and transport properties of all-manganite heterostructures consisting of ferromagnetic metallic electrodes separated by an antiferromagnetic barrier. We find…
Exchange induced charge inhomogeneities in rippled neutral graphene
L. Brey, J. J. Palacios
A new mechanism that induces charge density variations in corrugated graphene is proposed. Here it is shown how the interplay between lattice deformations and exchange interactions…
