二十多年前，纳米磁布尔逻辑的想法已提高。它设想使用具有两个稳定磁化方向的纳米磁铁作为实现逻辑门的原始二进制开关，并最终最终组合/顺序电路。关于纳米磁逻辑将如何蚀的热情宣言将蚀传统（基于晶体管）的逻辑电路扩散了应用物理学文献。二十年后，视线中没有一个可行的纳米磁性逻辑芯片，更不用说是商业上成功了。在这篇观点文章中，我提供了我的理由。我提出了对纳米磁逻辑的现实和脾气暴躁的愿景，指出了对这种范式的许多误解，在文献中出现的一些建议中存在缺陷，缺点以及可能阻碍该领域进展的陷阱。
The idea of nanomagnetic Boolean logic was advanced more than two decades ago. It envisaged the use of nanomagnets with two stable magnetization orientations as the primitive binary switch for implementing logic gates and ultimately combinational/sequential circuits. Enthusiastic proclamations of how nanomagnetic logic will eclipse traditional (transistor-based) logic circuits proliferated the applied physics literature. Two decades later there is not a single viable nanomagnetic logic chip in sight, let alone one that is a commercial success. In this perspective article, I offer my reasons for why this has come to pass. I present a realistic and tempered vision of nanomagnetic logic, pointing out many misconceptions about this paradigm, flaws in some proposals that appeared in the literature, shortcomings, and likely pitfalls that might stymie progress in this field.
