Shot noise in a diffusive F-N-F spin valve

  author={Eugene G. Mishchenko},
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.

Magneto shot noise in noncollinear diffusive spinvalves
We develop a semiclassical Boltzmann-Langevin theory of the spin polarized shot noise in a diffusive normal metal spin-valve connected by tunnel contacts to ferromagnetic reservoirs with noncollinear
Shot noise of charge and spin transport in a junction with a precessing molecular spin
Magnetic molecules and nanomagnets can be used to influence the electronic transport in mesoscopic junction. In a magnetic field the precessional motion leads to resonances in the dc- and
Spin-dependent shot noise in fractal semiconductor multilayers with two ferromagnetic contacts
We investigate the spin-dependent shot noise properties of electrons tunneling through fractal semiconductor multilayers (FSMs) sandwiched between two ferromagnets (Fs) with arbitrary relative
Shot noise of charge current and spin current in the presence of Rashba interaction
We study fluctuations of spin current and charge current of two-terminal systems in the presence of spin–orbit interaction. Based on the scattering matrix theory, we obtain the general expressions
Two-beam spin noise spectroscopy
We propose a method of two-beam spin noise spectroscopy to test the spin transport at equilibrium via analysis of correlations between time-shifted spin fluctuations at different space locations.
