Current polarity-dependent manipulation of antiferromagnetic domains (2018)
Journal Article
Wadley, P., Reimers, S., Grzybowski, M., Andrews, C., Wang, M., Chauhan, J., …Jungwirth, T. (in press). Current polarity-dependent manipulation of antiferromagnetic domains. Nature Nanotechnology, 13, doi:10.1038/s41565-018-0079-1. ISSN 1748-3387

Antiferromagnets have several favourable properties as active elements in spintronic devices, including ultra-fast dynamics, zero stray fields and insensitivity to external magnetic fields. Tetragonal CuMnAs is a testbed system in which the antiferro... Read More

Imaging current-induced switching of antiferromagnetic domains in CuMnAs (2017)
Journal Article
Grzybowski, M., Wadley, P., Edmonds, K., Beardsley, R., Hills, V. A., Campion, R., …Dhesi, S. (2017). Imaging current-induced switching of antiferromagnetic domains in CuMnAs. Physical Review Letters, 118(5), doi:10.1103/PhysRevLett.118.057701. ISSN 0031-9007

The magnetic order in antiferromagnetic materials is hard to control with external magnetic fields. Using X-ray Magnetic Linear Dichroism microscopy, we show that staggered effective fields generated by electrical current can induce modification of t... Read More

Electrical switching of an antiferromagnet (2016)
Journal Article
Wadley, P., Howells, B., Železný, J., Andrews, C., Hills, V., Campion, R., …Jungwirth, T. (2016). Electrical switching of an antiferromagnet. Science, 351(6273), doi:10.1126/science.aab1031. ISSN 0036-8075

Antiferromagnets are hard to control by external magnetic fields because of the alternating directions of magnetic moments on individual atoms and the resulting zero net magnetization. However, relativistic quantum mechanics allows for generating cur... Read More
