<p><i>Antiferromagnetic Spintronics: Spintronics without magnetic
fields</i></p>
<p><span style="font-size: 10pt">While known for a long time,
antiferromagnetically ordered systems have previously been
considered, as “interesting but useless”. However, since
antiferromagnets potentially promises faster operation,
enhanced stability and higher integration densities, they
could potentially become a game changer for new spintronic
devices such as magnetic memories. Here I will show how
antiferromagnets can be used as active spintronics devices by
demonstrating the key operations of “reading” [1], “writing”
[2], and “transporting information” [3] in antiferromagnets.
Beyond conventional collinear antiferromagnets, more complex
non-collinear antiferromagnets exhibit a range of exciting
properties including higher – order Hall effects that we have
recently studied [4].<br>
