Magnetoelectric coupling at the interface of BiFeO3/La0.7Sr0.3MnO3 multilayers
M. J. Calderon, S. Liang, R. Yu +6
Electric-field controlled exchange bias in a heterostructure composed of the ferromagnetic manganite La0.7Sr0.3MO3 and the ferroelectric antiferromagnetic BiFeO3 has recently been…
Excitonic Effects in Two-Dimensional Massless Dirac Fermions
Jianhui Wang, H. A. Fertig, Ganpathy Murthy +1
We study excitonic effects in two-dimensional massless Dirac fermions with Coulomb interactions by solving the ladder approximation to the Bethe-Salpeter equation. It is found that…
Effect of strain on the orbital and magnetic ordering of manganite thin films and their interface with an insulator
A. Baena, L. Brey, M. J. Calderon
We study the effect of uniform uniaxial strain on the ground state electronic configuration of a thin film manganite. Our model Hamiltonian includes the double-exchange, the Jahn-T…
Dirac Spectrum in Piecewise Constant One-Dimensional Potentials
D. P. Arovas, L. Brey, H. A. Fertig +2
We study the electronic states of graphene in piecewise constant potentials using the continuum Dirac equation appropriate at low energies, and a transfer matrix method. For superl…
Electronic transport through bilayer graphene flakes
J. W. Gonzalez, H. Santos, M. Pacheco +2
We investigate the electronic transport properties of a bilayer graphene flake contacted by two monolayer nanoribbons. Such a finite-size bilayer flake can be built by overlapping…
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…
