1. A two-terminal spin Hall oscillator comprising:
a spin current source; and
a free layer coupled to the spin current source,
wherein the free layer has a magnetization hard axis that is parallel to a quantization axis of a spin current injected due to a spin Hall effect of the spin current source.
