<p>Welcome to the University of Jyväskylä physics colloquium. This
week's colloquium is organized together with the <a href="https://www.jyfk.fi/en/">Physicist club</a> (<a href="https://www.jyfk.fi">Fyysikkokerho</a>), who has selected
the topic and the speaker. <br>

<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>

<p> Coffee will be served in the lobby. Although on-site attendance
is the preferred option, you can also join via Zoom. Please do not
send chat messages in Zoom during the talk, except if you need to
tell about a muted speaker. <br>
