Abstract

Magnetic Cellular Automata (MCA) is a novel take on an alternative technological actualization of Boolean logic machines. Not only has it been able to prototypically demonstrate successful operation of logical gates at room temperature; all key components necessary to implement any Boolean function has been realized. We present work further reducing the size of the single domain nano-magnet, approximately 100 times 50 times 30 nm, and physically implement two types of MCA wire architectures ferromagnetic and anti-ferromagnetic. We report the first physical implementation of shape engineered ferromagnetic wires and compare both wires under saturating magnetic fields in the Z direction. We have concluded experimentally, that for conventional data propagation between logical networks, ferromagnetic wires provide extremely stable operation. The high order of coupling we found under saturating magnetic fields demonstrates the flexible clocking nature of ferromagnetic wires and inches the technology closer to implementing complex circuitry.
