Abstract
The superconducting gap suppression under spin-polarized quasiparticle currents in ferromagnet-superconductor-ferromagnet single-electron transistors was reported. The superconducting gap was measured as a function of magnetic field. The superconducting gap was found to be strongly suppressed by polarized quasiparticle injection from the ferromagnetic leads if the magnetizations of the two leads were misaligned.
