Projeto e simulação de circuitos nanomagnéticos

Abstract

Nanomagnetic Logic (NML) is a new technology where logic operations are performed through dipolar magnetostatic interactions between nanosized magnetic specimens at room temperature. The low switching energies involved in the operation of NML circuits in addition to the possibility of higher integration density are remarkable advantages of this technology over CMOS-based systems. Although intense work have been done on the physical behavior of the NML systems, simulation tools for the study of complex NML architectures are lacking. In this work, we present a fast and robust computational tool to design and simulate NML circuits response, allowing the user to easily create complex magnetic circuits of arbitrary architecture, by placing rectangular shaped nanomagnets in a plane. This is the first NML simulation tool that takes into account the magnetostatic interaction between magnets under the influence of a magnetic field. Initial simulation results are encouraging and consistent with the experimental results in the literature.
