非中心对称(NCS)材料具有一系列令人兴奋的功能，如非线性光学(NLO)响应和拓扑自旋织构(Skyrmions)。虽然NLO材料和磁性天幕子表现出两套不同的物理性质，但它们的设计策略在原子尺度精度、结构定制和电子可调谐方面有着深刻的联系。尽管在单独研究这些系统方面取得了令人印象深刻的进展，但对于导航NCS材料的化学原理的联合路线图仍然难以捉摸。这篇综述结合了NCS系统的两个副主题，NLO材料和磁性天子，提供了一个多方面的叙述，说明如何在邀请社区创新方法的同时，将经常抽象的基本原理转化为目标功能。我们通过举例说明该领域的相关实例，概述了对所需属性至关重要的设计原则。我们用适当的电子结构补充材料化学，以展示基本原理的力量，以创建与倍频仪器和自旋电子设备中可预见的社会影响相关的系统集成。
Noncentrosymmetric (NCS) materials feature an exciting array of functionalities such as nonlinear optical (NLO) responses and topological spin textures (skyrmions). While NLO materials and magnetic skyrmions display two different sets of physical properties, their design strategies are deeply connected in terms of atomic-scale precision, structural customization, and electronic tunability. Despite impressive progress in studying these systems separately, a joint road map for navigating the chemical principles for NCS materials remains elusive. This review unites two subtopics of NCS systems, NLO materials and magnetic skyrmions, offering a multifaceted narrative of how to translate the often-abstract fundamentals to the targeted functionalities while inviting innovative approaches from the community. We outline the design principles central to the desired properties by exemplifying relevant examples in the field. We supplement materials chemistry with pertinent electronic structures to demonstrate the power of the fundamentals to create systems integration relevant to foreseeable societal impacts in frequency-doubling instrumentation and spin-based electronics.
