本文从化学视角综述交变磁性，探讨晶体化学、成键和电子结构如何实现该磁序，并总结材料家族、实验表征、计算发现策略及应用前景。
AI 中文摘要
磁性一直是化学、物理学和材料科学研究的核心主题，其中化学组成和成键在决定磁性行为方面起着关键作用。交变磁体是一类新发现的磁性材料，它们结合了传统铁磁体和反铁磁体的特征，源于特定的对称性和电子结构 motifs。在这篇综述中，我们提出了一个以化学为驱动的交变磁性观点，强调晶体化学、成键和电子结构如何实现这种非常规的磁有序。我们首先介绍理解交变磁体所需的基本概念，重点放在对称性考虑、轨道特征和电子结构特征上。然后，我们调查了已发现交变磁性的多种材料家族，关注有利于交变磁有序的配位环境和结构-性能关系。随后，我们介绍了用于表征交变磁性材料的实验方法。我们检验了从头算材料发现作为识别新型交变磁体的有前景策略，强调化学约束（如对称性和成键）如何指导计算搜索。除了其内在重要性外，交变磁体为技术提供了有趣的可能性。因此，我们强调了可能通过交变磁性材料实现的应用，以及它们与现有有序（如铁电性和超导性）的耦合。最后，我们指出了一些挑战和前景，其中基于化学的设计指南可以在推进交变磁性研究方面发挥重要作用。总之，这篇综述提供了交变磁性近期发展的概述，从基本概念到当前最先进水平。
英文摘要
Magnetism has been a central theme of research in chemistry, physics, and materials science, with chemical composition and bonding playing key roles in determining magnetic behavior. Altermagnets are a newly identified class of magnetic materials that combine features of conventional ferromagnets and antiferromagnets, arising from specific symmetry and electronic structure motifs. In this review, we present a chemistry-driven viewpoint on altermagnetism, highlighting how crystal chemistry, bonding, and electronic structure enable this unconventional magnetic order. We begin by introducing the fundamental concepts required to understand altermagnets, with an emphasis on symmetry considerations, orbital character, and electronic structure signatures. We then survey the diverse material families in which altermagnetism has been identified, drawing attention to coordination environments and structure-property relationships that favor altermagnetic order. We subsequently present experimental approaches which are useful for the characterization of altermagnetic materials. We examine ab initio materials discovery as a promising strategy for identifying new altermagnets, emphasizing how chemical constraints, such as symmetry and bonding, can guide computational searches. Other than their intrinsic importance, altermagnets provide interesting possibilities for technology. For this reason, we highlight possible applications that may be enabled through altermagnetic materials, along with their coupling with existing orders such as ferroelectricity and superconductivity. In conclusion, we point out some challenges and prospects, where chemically-based design guidelines can play an important role towards advancing altermagnetism research. In summary, this review offers an account of recent developments in altermagnetism, from basic concepts to the current state-of-the-art.
