Implementation of a nanomagnetic full adder circuit

The development and characterization of a nanomagnet full adder circuit is demonstrated. To our knowledge, this is the most complex magnetic circuit attempted to date. The circuit comprises 53 magnets that perform as three majority gates plus internal interconnections, with only one internal error. The inputs of the gate can be set independently, allowing an exhaustive test of the magnetic operation. Because completely error-free computing in this structure was not achieved, strategies to eliminate errors are proposed.
