Induced spin polarization via Andreev reflection from polarized phase of spin-triplet superconductor

We discuss the Andreev reflection at the interface of normal metal with spin triplet superconductor in the equal-spin pairing case. The pairing induces a net spin polarization on the normal side which should be detectable. With the presence of this polarization one can distinguish between the polarized triplet and the singlet pairings. It may also play an important role in detecting the triplet component in unconventional superconductors.
