摘要: We investigate the nonequilibrium transport properties of a quantum dot when spin flip processes compete with formation Kondo resonance in presence ferromagnetic leads. Based upon Anderson Hamiltonian strongly interacting limit, we predict splitting differential conductance scattering amplitude is order temperature. discuss how relative orientation lead magnetizations influences electronic current and shot noise nontrivial way. Furthermore, find that zero-bias tunneling magnetoresistance becomes negative increasing amplitude.
