Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As (2014)
Journal Article
Wang, M., Marshall, R., Edmonds, K., Rushforth, A., Campion, R., & Gallagher, B. (2014). Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As. Applied Physics Letters, 104, Article 132406. https://doi.org/10.1063/1.4870521

In this paper, we use simultaneous magnetometry and electrical transport measurements to critically examine ways in which the Curie temperature (TC) values have been determined in studies of dilute magnetic semiconductors. We show that, in sufficient... Read More about Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As.

An antidamping spin–orbit torque originating from the Berry curvature (2014)
Journal Article
Kurebayashi, H., Sinova, J., Fang, D., Irvine, A. C., Skinner, T. D., Wunderlich, J., …Jungwirth, T. (2014). An antidamping spin–orbit torque originating from the Berry curvature. Nature Nanotechnology, 9(3), 211-217. https://doi.org/10.1038/nnano.2014.15

Magnetization switching at the interface between ferromagnetic and paramagnetic metals, controlled by current-induced torques, could be exploited in magnetic memory technologies. Compelling questions arise regarding the role played in the switching b... Read More about An antidamping spin–orbit torque originating from the Berry curvature.

Dynamics of a vertical cavity quantum cascade phonon laser structure (2013)
Journal Article
Maryam, W., Akimov, A. V., Campion, R., & Kent, A. (2013). Dynamics of a vertical cavity quantum cascade phonon laser structure. Nature Communications, 4, Article 2184. https://doi.org/10.1038/ncomms3184

Driven primarily by scientific curiosity, but also by the potential applications of intense sources of coherent sound, researchers have targeted the phonon laser (saser) since the invention of the optical laser over 50 years ago. Here we fabricate a... Read More about Dynamics of a vertical cavity quantum cascade phonon laser structure.
