Antiferromagnetic Insulatronics: Spintronics without magnetic fields and Moving Electrons

MTL Seminar Series
Mathias Kläui, Johannes Gutenberg-University


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.
