Abstract
Spin current generators and systems and methods for employing spin current generators. A spin current generator may be configured to generate a spin current polarized in one direction, or a spin current selectively polarized in two directions. The spin current generator may by employed in spintronics applications, wherein a spin current is desired.
Claims31
A spin current generator comprising:
- at least one structure comprising a ferromagnetic layer and a nonmagnetic layer;
- and
- at least one gate configured to selectively apply a voltage to the at least one structure,
- wherein the spin current generator is configured to output a current.
1 more element
A system comprising:
- a programmable structure;
- and
- a spin current generator configured to generate a spin current through the programmable structure.
A method of operating a device comprising:
- transmitting, from a spin current generator, a first current having a first polarity through a structure of the device in a first direction;
- and
- transmitting, from the spin current generator, a second current having a second polarity through the structure in the first direction, wherein the first polarity is opposite the second polarity.
A method of operating a device comprising:
- transmitting, from a spin current generator, a first current having a polarity through a structure of the device in a first direction;
- and
- transmitting, from the spin current generator, a second current having a non polarity through the structure in the first direction.
