Abstract
Spin-polarized transport through an interacting single-level quantum dot coupled to two ferromagnetic leads with non-collinear magnetizations is analyzed theoretically by means of the nonequilibrium Green function technique. We show that spin precession on the dot, which arises due to an effective exchange field originating from the interaction between the dot and external electrodes, may lead to negative differential conductance. Our results also prove that the diode-like behavior in asymmetrical junctions with one electrode being half-metallic is partially suppressed when magnetic moments of the electrodes become non-collinear. © 2005 WILEY-VCH Verlag GmbH & Co.
