Tuning magnon spectra via interlayer coupling in pseudo-3D nanostructured artificial spin ice arrays (2023)
Journal Article
de Rojas, J., Atkinson, D., & Adeyeye, A. O. (2023). Tuning magnon spectra via interlayer coupling in pseudo-3D nanostructured artificial spin ice arrays. Applied Physics Letters, 123(23), Article 232407. https://doi.org/10.1063/5.0177447

We have investigated the static and dynamic behavior of “pseudo-3D” trilayer square artificial spin ice structures. The trilayer stack comprises of two ferromagnetic Ni81Fe19 (Permalloy, Py) layers with 30 and 70 nm thickness, separated by a nonmagne...

Non-uniform Gd distribution and magnetization profiles within GdCoFe alloy thin films (2023)
Journal Article
Inyang, O., Swindells, C., Rianto, D., Bouchenoire, L., Morris, R. J. H., Merkulov, A., …Atkinson, D. (2023). Non-uniform Gd distribution and magnetization profiles within GdCoFe alloy thin films. Applied Physics Letters, 123(12), Article 122403. https://doi.org/10.1063/5.0165423

Rare earth (RE):transition metal (TM) ferrimagnetic alloys continue to attract significant attention for spintronics. This work focuses on the elemental distribution of RE and TM elements throughout the thickness of nominally uniform films and the re...

Synthetic route to low damping in ferromagnetic thin-films (2023)
Journal Article
Azzawi, S., Umerski, A., Sampaio, L. C., Bunyaev, S. A., Kakazei, G. N., & Atkinson, D. (2023). Synthetic route to low damping in ferromagnetic thin-films. APL Materials, 11(8), Article 081108. https://doi.org/10.1063/5.0147172

Previous theory indicated that the individual monolayers within transition metal ferromagnet thin-films contribute different magnitudes to the total ferromagnetic damping. Here, the aim was to investigate if the thin-film damping could be reduced by... Read More about Synthetic route to low damping in ferromagnetic thin-films.
