“…[21] As a result, the AFM order in such antiferromagnets is tunable by electric currents but remains inert against moderate external magnetic disturbance. Note that the spin-flop fields of thin films of CuMnAs and Mn 2 Au were determined to be in the order of 1 or 10 T, [28][29][30][31] depending on thickness, temperature, and field directions. In addition, the Néel vector of Mn 2 Au was shown sensitive to electric-field-induced piezoelectric strain.…”

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.
