Tunnel magnetoresistance of magnetic molecules with spin-vibron coupling
Paper in proceedings, 2017

The effect of molecular vibrations on the tunnel magnetoresistance (TMR) of a mag- netic tunnel junction with a single spin-anisotropic molecule interconnecting its elec- trodes is investigated theoretically. We demonstrate that if these vibrations couple at the same time to the charge of tunneling electrons and to the spin of the molecule, the spin anisotropy of such a molecule becomes enhanced. This has, in turn, a profound impact on the TMR of such a device showing that molecular vibrations lead to a significant change of spin-polarized transport, differing for the parallel and antiparallel magnetic configuration of the junction.
