Welcome to the University of Jyväskylä physics colloquium. This week's colloquium is organized together with the Physicist club [https://www.jyfk.fi/en/] (Fyysikkokerho [https://www.jyfk.fi]), who has selected the topic and the speaker.

On Friday 3rd November at 10 am in FYS1 and Zoom [https://jyufi.zoom.us/j/66703175507] (passcode 890524):
Mathias Kläui, Gutenberg University of Mainz and NTNU Norway:
Antiferromagnetic Spintronics: Spintronics without magnetic fields
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].
