New developments in spintronics based on antiferromagnetic materials show promise for improved fundamental understanding and applications in technology.

Spintronics has revolutionized the field of magnetic recording and it is hoped that it will complement semiconductor-based microelectronics in ‘beyond Moore’s law’ information technologies. Whether designed for sensing, memory or logic applications, spintronic devices have been traditionally based on ferromagnetic materials. Here we present a brief overview of an emerging subfield of spintronics research in which antiferromagnets take the central role. We focus on the latest developments, which range from demonstrations of experimental microelectronic memory devices and optical control of antiferromagnetic spins to the interplay of antiferromagnetic spintronics with topological phenomena, noncollinear antiferromagnets, antiferromagnet/ferromagnet interfaces and synthetic antiferromagnets. We illustrate that the envisaged applications of antiferromagnetic spintronics may expand to areas as diverse as terahertz information technologies or artificial neural networks.
