Abstract
Spin-dependent tunneling through a quantum dot coupled to one ferromagnetic and one superconducting electrodes is studied theoretically in the Andreev re ection (AR) regime. Spectral functions for the system are calculated in terms of the nonequilibrium Green function technique. E ects due to interplay between the Coulomb correlations on the dot and the local phonon mode in the context of the AR transmission are analyzed.
