A Novel Crossing Device for in-plane Nanomagnetic Logic Circuits

摘要

Nanomagnetic logic (NML) circuits provide an efficient way to overcome the physical and thermal limits of charge-based logic devices. They present very low power consumption, making them very attractive to be employed as remote devices in the field of Internet of Things (IoT) technology. When designing complex nanomagnetic circuits, we often need a circuit device to perform the crossing of information without the necessity of extra layer of interacting magnets. In this work, we propose and analyze the behavior of a structure that allows an in-plane crossing of information that can be useful in the design of complex NML circuits. Micromagnetic simulation through the Object Oriented Micro-Magnetic Framework (OOMMF) was performed by inserting the device on the desired crossing spot and driving all magnets using external magnetic fields as clock signals. We show that the proposed circuit can horizontally and vertically cross the signal data, extending its usage to antiferromagnetic ally and ferromagnetically coupled wires.
