It is shown that when a spin-polarized current is injected into a superconductor from a ferromagnet in ferromagnet/superconductor (FM/SC) and FM/SC/FM tunnel junctions, the spin and charge degrees of freedom of electrons are carried by quasi-particles and Cooper pairs in SC, respectively. The spin accumulation competes with the superconductivity and the spin current gives rise to the transverse charge current in SC.
