Antiferromagnets constitute promising contender materials for next-generation spintronic devices with superior stability, scalability, and dynamics. Nevertheless, the perception of well-established ferromagnetic spintronics underpinned by spontaneous magnetization seemed to indicate the inadequacy of antiferromagnets for spintronics—their compensated magnetization has been perceived to result in uncontrollable antiferromagnetic order and subtle magnetoelectronic responses. However, remarkable advancements have been achieved in antiferromagnetic spintronics in recent years, with consecutive unanticipated discoveries substantiating the feasibility of antiferromagnet-centered spintronic devices. It is emphasized that, distinct from ferromagnets, the richness in complex antiferromagnetic crystal structures is the unique and essential virtue of antiferromagnets that can open up their endless possibilities of novel phenomena and functionality for spintronics. In this Perspective, the recent progress in antiferromagnetic spintronics is reviewed, with a particular focus on that based on several kinds of antiferromagnets with special antiferromagnetic crystal structures. The latest developments in efficiently manipulating antiferromagnetic order, exploring novel antiferromagnetic physical responses, and demonstrating prototype antiferromagnetic spintronic devices are discussed. An outlook on future research directions is also provided. It is hoped that this Perspective can serve as guidance for readers who are interested in this field and encourage unprecedented studies on antiferromagnetic spintronic materials, phenomena, and devices.

用于自旋电子学的新兴反铁磁体
反铁磁体是下一代自旋电子器件的有前途的竞争材料，具有卓越的稳定性、可扩展性和动态性。然而，对以自发磁化为基础的完善的铁磁自旋电子学的看法似乎表明反铁磁体对于自旋电子学的不足——它们的补偿磁化被认为会导致不可控的反铁磁序和微妙的磁电子响应。然而，近年来反铁磁自旋电子学取得了显着的进展，连续的意想不到的发现证实了以反铁磁体为中心的自旋电子器件的可行性。需要强调的是，与铁磁体不同，复杂的反铁磁晶体结构的丰富性是反铁磁体独特而本质的优点，可以为自旋电子学的新现象和功能开辟无限的可能性。本文综述了反铁磁自旋电子学的最新进展，特别重点介绍了基于几种具有特殊反铁磁晶体结构的反铁磁体的自旋电子学研究进展。讨论了有效操纵反铁磁秩序、探索新颖的反铁磁物理响应以及演示反铁磁自旋电子器件原型的最新进展。还对未来的研究方向进行了展望。希望本文能够为对该领域感兴趣的读者提供指导，并鼓励对反铁磁自旋电子材料、现象和器件进行前所未有的研究。
