File talk:Spin-valve GMR.svg

Incoming spin directions should be: the upper one up, the lower one down. It is because parallel spin electrons have an energetically better position than anti-parallel spin electrons, therefore they scatter less.

Totally wrong picture
The spin scattering is wrong. on the parallel (left) set up, the spin up electrons wont get scattered at all. so the path has to be like the path from the spin down electrons. Furthermore the scattering only takes place at the intersection between FM and NM (blue to orange and orange to blue). You indicated a scattering in the FM which is wrong. The picture you previously uploaded (16:39, 14 November 2009) was correct in terms of scattering. Please correct this ASAP, because a lot of people will google this effect Of course you have to switch the resistors too
