GHz frequency layered antiferromagnets for novel Magnonic computing applications — •Sally Lord and John Gregg — Clarendon Laboratory, Department of Physics, University of Oxford, Parks Road, Oxford, OX1 3PU, United Kingdom

Magnonic computing is a novel computing paradigm that exploits the unusual behaviour of magnons to develop faster, more efficient devices, that have the potential to rival existing CMOS technologies. Antiferromagnetic materials are a prime candidate for such applications, primarily due to their typical THz resonant frequencies, which offer the possibility of creating devices with faster operating speeds. However, studying the THz frequencies of these materials, using conventional electronic methods, is challenging. Layered antiferromagnetic materials offer a promising solution to this challenge, since the weak interlayer coupling results in resonant frequencies that exist in the easily accessible microwave range. Furthermore, these materials can be artificially created by coupling two ferromagnetic layers via a non-magnetic spacer layer to create synthetic antiferromagnet. In this contribution, we report on the experimental setup designed to explore the magnetic properties of such materials.
