Enhanced skyrmion metastability under applied strain in FeGe (2022)
Journal Article
Littlehales, M., Turnbull, L., Wilson, M., Birch, M., Popescu, H., Jaouen, N., Verezhak, J., Balakrishnan, G., & 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.

Confinement of Skyrmions in Nanoscale FeGe Device-like Structures (2022)
Journal Article
Twitchett-Harrison, A. C., Loudon, J. C., Pepper, R. A., Birch, M. T., Fangohr, H., Midgley, P. A., Balakrishnan, G., & Hatton, P. D. (2022). Confinement of Skyrmions in Nanoscale FeGe Device-like Structures. ACS Applied Electronic Materials, 4(9), 4427 - 4437. https://doi.org/10.1021/acsaelm.2c00692

Skyrmion-based devices have been proposed as a promising solution for low-energy data storage. These devices include racetrack or logic structures and require skyrmions to be confined in regions with dimensions comparable to the size of a single skyr...

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., Verezhak, J., Balakrishnan, G., & 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.

Toggle-like current-induced Bloch point dynamics of 3D skyrmion strings in a room temperature nanowire (2022)
Journal Article
Birch, M., Cortés-Ortuño, D., Litzius, K., Wintz, S., Schulz, F., Weigand, M., Štefančič, A., Mayoh, D., Balakrishnan, G., Hatton, P., & Schütz, G. (2022). Toggle-like current-induced Bloch point dynamics of 3D skyrmion strings in a room temperature nanowire. Nature Communications, 13(1), Article 3630. https://doi.org/10.1038/s41467-022-31335-y

Research into practical applications of magnetic skyrmions, nanoscale solitons with interesting topological and transport properties, has traditionally focused on two dimensional (2D) thin-film systems. However, the recent observation of novel three... Read More about Toggle-like current-induced Bloch point dynamics of 3D skyrmion strings in a room temperature nanowire.
