Abstract
Illustrative embodiments of all-spin logic devices, circuits, and methods are disclosed. In one embodiment, an all-spin logic device may include a first nanomagnet, a second nanomagnet, and a spin-coherent channel extending between the first and second nanomagnets. The spin-coherent channel may be configured to conduct a spin current from the first nanomagnet to the second nanomagnet to determine a state of the second nanomagnet in response to a state of the first nanomagnet.
Claims27
An all-spin logic device comprising:
- a first nanomagnet;
- a second nanomagnet;
- and
- a spin-coherent channel extending between the first and second nanomagnets, the spin-coherent channel configured to conduct a spin current from the first nanomagnet to the second nanomagnet to determine a state of the second nanomagnet in response to a state of the first nanomagnet.
An all-spin logic circuit comprising:
- a first nanomagnet having an input side and an output side;
- a second nanomagnet having an input side and an output side;
- a third nanomagnet having an input side and an output side;
- a first spin-coherent channel configured to conduct a spin current generated from the input side of the first nanomagnet to the output side of the second nanomagnet;
- and
- a second spin-coherent channel configured to conduct a spin current generated from the input side of the second nanomagnet to the output side of the third nanomagnet.
A method comprising:
- applying a voltage to a first nanomagnet to generate a first spin current in response to a magnetization direction of the first nanomagnet;
- and
- routing the first spin current along a first spin-coherent channel to a second nanomagnet to determine a magnetization direction of the second nanomagnet.
