TMR Effect in a FM-QD-FM System
Using the Keldysh nonequilibrium technique, we study current and the tunnelling magnetoresistance (TMR)in a quantum dot coupled to two ferromagnetic leads (FM-dot-FM). The current is calculated for both paralleland antiparallel lead alignments. Coulomb interaction and spin-flip scattering are taken...
