Journal Article
Littlehales, M. T., Moody, S. H., Bereciartua, P. J., Mayoh, D. A., Parkin, Z. B., Blundell, T. J., Unsworth, E., Francoual, S., Balakrishnan, G., Alba Venero, D., & Hatton, P. D. (2024). Spin density waves and ground state helices in EuGa2.4Al1.6. Physical Review Research, 6(3), Article L032015. https://doi.org/10.1103/physrevresearch.6.l032015

The Eu⁢(Ga1−𝑥⁢Al𝑥)4 series is composed of centrosymmetric structures which exhibit a wide range of rich topological phenomena, including some members hosting magnetic skyrmions. In this letter, we investigate the previously unreported intermediate co... Read More about Spin density waves and ground state helices in EuGa2.4Al1.6.

Demonstration of Controlled Skyrmion Injection Across a Thickness Step (2024)
Journal Article
Littlehales, M. T., Moody, S. H., Turnbull, L. A., Huddart, B. M., Brereton, B. A., Balakrishnan, G., Fan, R., Steadman, P., Hatton, P. D., & Wilson, M. N. (2024). Demonstration of Controlled Skyrmion Injection Across a Thickness Step. Nano Letters, 24(22), 6813-6820. https://doi.org/10.1021/acs.nanolett.4c01605

Spintronic devices incorporating magnetic skyrmions have attracted significant interest recently. Such devices traditionally focus on controlling magnetic textures in 2D thin films. However, enhanced performance of spintronic properties through the e... Read More about Demonstration of Controlled Skyrmion Injection Across a Thickness Step.

Enhanced skyrmion metastability under applied strain in FeGe (2022)
Journal Article
Littlehales, M., Turnbull, L., Wilson, M., Birch, M., Popescu, H., Jaouen, N., …Hatton, P. (2022). Enhanced skyrmion metastability under applied strain in FeGe. Physical Review B, 106(21), Article 214434. https://doi.org/10.1103/physrevb.106.214434

Mechanical straining of skyrmion hosting materials has previously demonstrated increased phase stability through the expansion of the skyrmion equilibrium pocket. Additionally, metastable skyrmions can be generated via rapid field cooling to form sig... Read More about Enhanced skyrmion metastability under applied strain in FeGe.

X-ray holographic imaging of magnetic surface spirals in FeGe lamellae (2022)
Journal Article
Turnbull, L., Littlehales, M., Wilson, M., Birch, M., Popescu, H., Jaouen, N., …Hatton, P. (2022). X-ray holographic imaging of magnetic surface spirals in FeGe lamellae. Physical Review B, 106(6), Article 064422. https://doi.org/10.1103/physrevb.106.064422

Isotropic helimagnets are known to host a diverse range of chiral magnetic states. In 2016, Rybakov et al., theorized the presence of a surface-pinned stacked spin spiral phase [F. N. Rybakov et al., New J. Phys. 18, 045002 (2016)], which has yet to... Read More about X-ray holographic imaging of magnetic surface spirals in FeGe lamellae.
