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…
Skyrmion Strings and Anomalous Hall Effect in Double Exchange Systems
M. J. Calderon, L. Brey
We perform Monte Carlo simulations to obtain quantitative results for the anomalous Hall resistance, R_A, observed in colossal magnetoresistance manganites. R_A arises from the int…
Conductance as a Function of the Temperature in the Double Exchange Model
M. J. Calderón, J. A. Vergés, L. Brey
We have used the Kubo formula to calculate the temperature dependence of the electrical conductance of the double exchange Hamiltonian. We average the conductance over an statistic…
Monte Carlo Simulations for the Magnetic Phase Diagram of the Double Exchange Hamiltonian
M. J. Calderon, L. Brey
We have used Monte Carlo simulation techniques to obtain the magnetic phase diagram of the double exchange Hamiltonian. We have found that the Berry's phase of the hopping amplitud…
