## Abstract Electron tunneling through a spinβsplit discrete level of an interacting quantum dot coupled to two ferromagnetic electrodes with nonβcollinear magnetizations is investigated theoretically by means of the nonequilibrium Green function approach. It is shown that the spin splitting of the
We investigate the Kondo effect of a multiorbital quantum dot coupled to spin polarized leads, using the noncrossing approximation. It is shown that as the spin polarization is increased, the Kondo peak splits into three peaks and the middle one is located close to the Fermi energy. The results indi
