该综述探讨曲线磁性中几何形状、电子能带与自旋织构的耦合效应,提出“元几何”材料设计新概念,以推动节能可扩展纳米电子学发展。

AI 中文摘要

为了在纳米技术中实现新概念,基于基础材料科学和物理学的最新发现,设计具有定性新性能的材料是富有洞察力的。曲线磁性作为一种利用物体几何形状和拓扑效应在纳米尺度设计手性和各向异性响应的工具而出现。这一概念与材料筛选截然不同但又互补,后者主要基于优化内在微观性质以修改磁织构用于特定应用。当代曲线磁性聚焦于平均场微磁学,而晶格结构和电子自由度的显式贡献仍未被考虑。在本综述中,我们将强调在考虑这种耦合时出现的效应,这些效应已导致设计“元几何”材料的新概念。该领域的进一步发展将为曲线磁性纳米结构的基础理解及其在节能和可扩展纳米电子学中的应用提供有吸引力的技术前景。

英文摘要

To enable novel concepts in nanotechnologies, it is insightful to design materials with qualitatively new performances originating from recent discoveries in fundamental material science and physics. Curvilinear magnetism emerged as a tool to design chiral and anisotropic responses of materials at the nanoscale using the effects of the geometric shape and topology of the object. This concept is distinct yet complementary to material screening, which is primarily based on the optimization of intrinsic microscopic properties to modify magnetic textures for specific applications. Contemporary curvilinear magnetism focuses on mean-field micromagnetics, while the explicit contribution of the lattice structure and electronic degrees of freedom remains beyond consideration. In this review, we will emphasize on the effects which appear when this coupling is accounted for and that have resulted in novel concepts for the design of ``metageometric'' materials. Further development of this field will provide appealing technological prospects for fundamental understanding of curvilinear magnetic nanostructures and their applications in energy efficient and scalable nanoelectronics.
