Abstract	We have explored the spin polarisation of excited electrons in amorphous ferromagnetic iron?boron alloy by spin-resolved two-photon photoemission. These measurements were carried out with a spin resolved electron Time-of-Flight (ToF) analyser combined to a femtosecond laser source. The low kinetic energy was probed by caesium preparation of the sample surface. A constant spin polarisation of 18% was measured in the energy region between 1.3 and 3.2 eV above the Fermi level. The magnetic properties of the sample were characterised by a spin-resolved square hysteresis loop.
