Owing to the bistable character of the single molecular magnet (SMM), it can generate 100% spin-polarized currents even connected with normal (N) leads. In this work, we study the phonon-assisted spin current in N-SMM-N systems. We mainly focus on the interplay of SMM's bistable character and electron–phonon coupling. It is found that when SMM is trapped in one of the lowest bistable states, it can generate phonon-assisted spin-polarized currents. At the up-spin transport channel, it is accompanied by a phonon-assisted up-spin current, while at the down-spin transport channel, it is accompanied by a phonon-assisted down-spin current.
