Magnetic cellular automata coplanar cross wire systems

Quantum cellular automata has proposed an exclusive architecture where two coplanar perpendicular wires have the ability to intersect one another without signal degradation. The physical realization of cross wire architectures has yet to be implemented and researchers share concerns over the reliability of such a system. Here we have designed a coplanar cross wire layout for magnetic cellular automata (MCA) and have fabricated two different systems. The first system was implemented via two ferromagnetic coupled coplanar crossing wires and demonstrated all possible logic combinations. The second more complex cross wire system consisted of nine junctions and one hundred and twenty single domain nanomagnets. The complex system's ability to reach an energy minimum combined with the demonstration of all combinations of the smaller system leads us to conclude that a cross wire system is physically feasible and reliable in MCA.
