Journal Article
Wadley, P., Edmonds, K., Shahedkhah, M., Campion, R., Gallagher, B., Železný, J., …Dhesi, S. (in press). Control of antiferromagnetic spin axis orientation in bilayer Fe/CuMnAs films. Scientific Reports, 7, Article 11147. https://doi.org/10.1038/s41598-017-11653-8

Using x-ray magnetic circular and linear dichroism techniques, we demonstrate a collinear exchange coupling between an epitaxial antiferromagnet, tetragonal CuMnAs, and an Fe surface layer. A small uncompensated Mn magnetic moment is observed which i... Read More about Control of antiferromagnetic spin axis orientation in bilayer Fe/CuMnAs films.

Investigation of exchange coupled bilayer Fe/CuMnAs by pump-probe experiment (2017)
Journal Article
Saidl, V., Němec, P., Wadley, P., Edmonds, K., Campion, R., Novák, V., …Trojánek, F. (in press). Investigation of exchange coupled bilayer Fe/CuMnAs by pump-probe experiment. physica status solidi (RRL) - Rapid Research Letters, 11(4), https://doi.org/10.1002/pssr.201600441

Time-resolved pump-probe magneto-optical method was used to study Fe/CuMnAs bilayer. The probe polarization dependence was used to identify and separate parts of detected signals due to Faraday and Voigt magneto-optical effects that provide informati...
