摘要：

We observed the suppression of the superconductivity in a mesoscopic superconducting Al wire in proximity contact with an overlaid ferromagnetic Co wire. Finite voltages over a certain length of Al wire occurred as evidence for the suppression of the superconductivity while the spin-polarized currents were injected through the Co/Al interfaces and the spin diffusion length in the superconductor, estimated from the finite voltages, turned out to be related to the pair-condensing relaxation of quasiparticles through opposite spin channels.
