In this paper, we investigate the spin-current and its shot-noise spectrum in a single-molecule quantum dot coupled with a local phonon mode. We pay special attention to the effect of the phonon on the quantum transport property. The spin-polarization-dependent current is generated by a rotating magnetic field applied in the quantum dot. Our results show the remarkable influence of phonon mode on the zero-frequency shot noise. The electron-phonon interaction leads to sideband peaks that are located exactly on the integer number of the phonon frequency, and moreover, the peak height is sensitive to the electron-phonon coupling.
