Past studies have demonstrated that logic states can be represented using the rotation of the magnetization at flux-closed remanence in individual ferromagnetic disks. In this work, we present the results of micro-magnetic simulations of touching circular elements that can be used for room operable magnetic quantum cellular automata. Like gears in a mechanical system, the chirality of the magnetization alternates from element to element, as determined through interaction with neighbors. The switching of touching symmetric elements occurred when the applied field was removed, meaning minimal energy loss during the process. Maintaining coherence of opposite chirality in chains of elements could be achieved with the introduction of a biasing element to eliminate the bidirectionality of interaction. |
