Abstract:
The splitting of the Kondo Resonance (KR) in a quantum dot (QD) connected to ferromagnetic leads is studied using a new Slave Boson formulation. We show that the KR is splitted into two resonances out of the Fermi level. The splitting can be controlled by the application of a magnetic field in the QD. While this magnetic field does not modify the magnetism of the leads, it can restore the KR at the Fermi level. When the magnetization is strong enough, it's not possible to recover the KR. In addition, selective spin transport across the QD can be achieved by tuning the magnetic field. This effect is a consequence of the asymmetric Kondo splitting produced by the magnetic leads. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
