Special attention is paid on the spin accumulation and spin current caused by spin injection into non-magnetic metals and semiconductors and superconductors. A variety of phenomena induced in nano-superconductor/ferromagnet devices are proposed, examining the spin-charge separation in superconductors.6 pages, 5 figuresMesoscale and Nanoscale PhysicsSuperconductivitytext
