Abstract: | We investigate the spin-flip process through double quantum dots
coupled to two half-metallic ferromagnetic leads in series. By means
of the slave-boson mean-field approximation, we calculate the
density of states in the Kondo regime for two different
configurations of the leads. It is found that the transport shows
some remarkable properties depending on the spin-flip strength.
These effects may be useful in exploiting the role of electronic
correlation in spintronics. |
