Abstract: Antiferromagnetically ordered systems have previously been considered as “interesting but useless”. However, they promise faster operation, enhanced stability and higher integration density and could thus become a game changer for devices. Here I will show how antiferromagnets can be used as active spintronics devices by demonstrating the key operations of “writing” [1], “reading” [2] and “transporting information” [3] in antiferromagnets.

Bio: Mathias Kläui is professor of physics at Johannes Gutenberg-University Mainz and adjunct professor at the Norwegian University of Science and Technology. He received his PhD at the University of Cambridge, after which he joined IBM and became full professor in 2010. His research focuses on nanomagnetism and spin dynamics on the nanoscale in new materials.
