Spin-dependent tunneling through a quantum dot coupled to one ferromagnetic and one superconducting electrodes is studied theoretically in the Andreev reflection regime. Electrical conductance is calculated in terms of the nonequilibrium Green function technique. Effects due to the Zeeman splitting of the dot level are analyzed in both linear and nonlinear transport regimes, and are compared with the corresponding effects due to coherent intradot spin rotation.
