| Popis: | Using an equation-of-motion technique, we theoretically study the Fano{Kondo efiect in the T-shaped double quantum dots coupled to two ferromagnetic leads by the Anderson Hamiltonian. We calculate the density of states in this system with both parallel and antiparallel lead-polarization alignments, and our results reveal that the interdot coupling, the spin-polarized strength and the energy level of the side coupled quantum dot greatly in∞uence the density of states of the central quantum dot. This system is a possible candidate for spin valve transistors and may have potential applications in the spintronics. |
