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…
