Shot noise in a diffusive F-N-F spin valve
arXiv:cond-mat/0305003 · doi:10.1103/PhysRevB.68.100409
Abstract
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.
