Abstract
Spin polarized apparatus includes a spin polarizing section of magnetic material with an electron input port and a polarized electron port and a transport section of magnetic material with a polarized electron input port electrically coupled to the polarized electron port of the polarizing section and an electron output port. Electrons traversing the polarizing section all have similar spin directions at the output dependent upon the magnetization direction of the polarizing section. Electrons traversing the transport section all have spins in a first direction at the output. The cell has a low resistance when the magnetization direction of the polarizing section is in the first direction (electrons entering the transport section all have spins in the first direction) and a high resistance when the magnetization direction is in an opposite direction (electrons entering the transport section all have spins in the opposite direction).
