Abstract
Described is an oscillating apparatus which comprises: an interconnect with spin-coupling material (e.g., Spin Hall Effect (SHE) material); and a magnetic stack having two magnetic layers such that one of the magnetic layers is coupled to the interconnect, wherein each of the two magnetic layers have respective magnetization directions to cause the magnetic stack to oscillate.

An apparatus comprising:
- a first oscillator including:
- a first interconnect with Spin Hall Effect (SHE) material;
- and
- a first magnetic stack having two magnetic layers such that one of the magnetic layers is coupled to the first interconnect, wherein each of the two magnetic layers have respective magnetization directions to cause the first magnetic stack to oscillate a signal on the first interconnect;
- a second oscillator including:
- a second interconnect with SHE material;
- and a second magnetic stack having two magnetic layers such that one of the magnetic layers is coupled to the second interconnect, wherein each of the two magnetic layers have respective magnetization directions to cause the second magnetic stack to oscillate a signal on the second interconnect;
- and a coupling circuit to couple the first oscillator to the second oscillator, wherein the coupling circuit comprises a transistor with a controllable gate terminal, and with source and drain terminals coupled to the first and second interconnects respectively.
