Journal Article
Wadley, P., Howells, B., Železný, J., Andrews, C., Hills, V., Campion, R. P., Novák, V., Olejnik, K., Maccherozzi, F., Dhesi, S. S., Martin, S. Y., Wagner, T., Wunderlich, J., Freimuth, F., Mokrousov, Y., Kunes, J., Chauhan, J., Grzybowski, M. J., Rushforth, A. W., Edmonds, K. W., …Jungwirth, T. (2016). Electrical switching of an antiferromagnet. Science, 351(6273), 587-590. https://doi.org/10.1126/science.aab1031

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 about Electrical switching of an antiferromagnet.
