Magnetic and Metallic State at Intermediate Hubbard U Coupling in Multiorbital Models for Undoped Fe Pnictides
Rong Yu, Kien T. Trinh, Adriana Moreo +4
Multi-orbital Hubbard model Hamiltonians for the undoped parent compounds of the Fe-pnictide superconductors are here investigated using mean-field techniques. For a realistic four…
Model for the Magnetic Order and Pairing Channels in Fe Pnictide Superconductors
M. Daghofer, A. Moreo, J. A. Riera +3
A two-orbital model for Fe-pnictide superconductors is investigated using computational techniques on two-dimensional square clusters. The hopping amplitudes are derived from orbit…
Numerical study of finite size effects in the one-dimensional two-impurity Anderson model
S. Costamagna, J. A. Riera
We study the two-impurity Anderson model on finite chains using numerical techniques. We discuss the departure of magnetic correlations as a function of the interimpurity distance…
Large Magnetoresistance in a Manganite Spin-Tunnel-Junction Using LaMnO3 as Insulating Barrier
S. Yunoki, E. Dagotto, S. Costamagna +1
A spin-tunnel-junction based on manganites, with LaSrMnO (LSMO) as ferromagnetic metallic electrodes and the undoped parent compound LaMnO (LMO) as insulating b…
