这里,引入了一种人造自旋冰晶格,由于在晶胞中包含了耦合的纳米磁体,因此在特定的场切换协议下表现出独特的伊辛和非伊辛行为。在伊辛政权中,相对于晶格单位晶胞,展示了一种磁切换机制,该机制根据场的对准产生状态的单峰分布或双峰分布。此外,一种在整个晶格中产生大量随机分布的能量状态的方法,由伊辛和兰道州组成,通过磁力显微镜和微磁建模进行了研究。已经证明,晶格上的分散能量分布是本征设计的结果,可以通过控制临界场的入射角来微调。本手稿探索了16顶点Ising模型之外的复杂沮丧环境,以开发基于逻辑的新颖技术。
Here, an artificial spin ice lattice is introduced that exhibits unique Ising and non-Ising behavior under specific field switching protocols because of the inclusion of coupled nanomagnets into the unit cell. In the Ising regime, a magnetic switching mechanism that generates a uni- or bimodal distribution of states dependent on the alignment of the field is demonstrated with respect to the lattice unit cell. In addition, a method for generating a plethora of randomly distributed energy states across the lattice, consisting of Ising and Landau states, is investigated through magnetic force microscopy and micromagnetic modeling. It is demonstrated that the dispersed energy distribution across the lattice is a result of the intrinsic design and can be finely tuned through control of the incident angle of a critical field. The present manuscript explores a complex frustrated environment beyond the 16-vertex Ising model for the development of novel logic-based technologies.
