The Kondo effect in quantum dots coupled to ferromagnetic leads with noncollinear magnetizations: effects due to electron–phonon coupling

Spin-polarized transport through a quantum dot strongly coupled to ferromagnetic electrodes with noncollinear magnetic moments is analysed theoretically in terms of the nonequilibrium Green function formalism based on the equation of motion method. Electrons in the dot are assumed to be coupled to a phonon bath. The influence of electron-phonon coupling on tunnelling current, linear and nonlinear conductance, and tunnel magnetoresistance is studied in detail. Variation of the main Kondo peaks and phonon satellites with the angle between the magnetic moments of the leads is analysed.
