Fluctuations of electric current in a spin valve consisting of a diffusive
conductor connected to ferromagnetic leads and operated in the giant
magnetoresistance regime are studied. It is shown that a new source of
fluctuations due to spin-flip scattering enhances strongly shot noise up to a
point where the Fano factor approaches the full Poissonian value.
