Theory of the spin-dependent transport in superconducting quantum point contacts with a ferromagnetic metal

We calculate the tunneling conductance numerically in ferromagnetic metal/superconducting quantum wire/superconductor junctions. It is shown that a wide variety of the tunneling conductance is obtained depending on the exchange interaction in the ferromagnet and the geometry of the quantum wire.
