Abstract
A device including a spin channel to transport a spin current, a nano-oscillator, and a magnetoresistive device that receives the spin current from the nano-oscillator. The nano-oscillator includes a magnetization state that oscillates between a first state and a second state in response to an input voltage or current. The oscillation of the nano-oscillator may induce the spin current within the spin channel. The magnetoresistive device includes a magnetization state that is set based at least in part on the received spin current.

A device comprising:
- a spin channel to transport a spin current;
- a nano-oscillator having a magnetization state that, in response to a DC input voltage or current, oscillates between a first state and a second state and induces the spin current within the spin channel;
- and
- a magnetoresistive device that receives the spin current from the nano-oscillator, the magnetoresistive device having a magnetization state that is set to a parallel or anti-parallel state by the received spin current.
A method comprising:
- applying a DC input voltage or current to a nano-oscillator to oscillate a magnetization state of the nano-oscillator between a first state and a second state and induce a spin current in a spin channel coupled to the nano-oscillator;
- and
- setting, in response to the spin current, a magnetization state of a magnetoresistive device coupled to the spin channel, wherein the magnetization state of the magnetoresistive device is set to one of a parallel or anti-parallel state by the received spin current.
A logic device comprising:
