Abstract

We have investigated the effect of electron-phonon interaction on the spin-dependent transport through a La@C82endohedral fullerene based on the Green's function method and Landauer- Bütikker formalism. Effect of electron-phonon (e-ph) interaction is studied using Bütikker formalism. We have studied the influence of e-ph interaction on the spin dependent currents, and tunnel magnetoresistance (TMR) of the junction. Our results indicate that in the presence of e-ph interaction, the spin dependent currents increase but the TMR reduces. Furthermore, we have investigated the effect of the strength of coupling between electrode and molecule on the current-voltage characteristics of the junction. It is shown that the transport properties of molucle are obviously affected by the change of electrode/molecule coupling strength.
