Abstract
A circuit element includes first and second nanomagnets and first and second fixed magnets. The first nanomagnet is inductively coupled to a first current carrying element, and is configured to change polarity responsive to current in the first current carrying element. In one example, the first current carrying element includes a spin Hall effect substrate. The second nanomagnet is magnetically coupled to the first nanomagnet, and is inductively coupled to a second current carrying element. The first fixed magnet is disposed on the second nanomagnet and has a first fixed polarity, and second fixed magnet disposed on the second nanomagnet and has a second fixed polarity.
