Spin Polarization: Definition & Spintronics Logic Levels

[faraznizamani]

Can any give me a general idea of what is Spin Polarization ? and how can spin polarized electrons define logic levels(Spintronics) ?

Did you try searching for it? E.g. http://en.wikipedia.org/wiki/Spin_polarization

I don't know how magnetic polarization can account for defining logic levels ? as with each spin quantum number (1/2) the logic level shifts, I am just confused about the application of spin polarization within discrete electronics..
