We report spatially resolved small-angle neutron-scattering measurements of the conical and skyrmion states of a bulk single crystal of nickel-substituted Cu2OSeO3, with a nominal concentration of Ni of 14%. We observe a significant spatial dependenc... Read More about Position-dependent stability and lifetime of the skyrmion state in nickel-substituted Cu2OSeO3.

Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae (2020)
Journal Article
Turnbull, L. A., Birch, M. T., Laurenson, A., Bukin, N., Burgos-Parra, E. O., Popescu, H., Wilson, M. N., Stefančič, A., Balakrishnan, G., Ogrin, F. Y., & Hatton, P. D. (2021). Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae. ACS Nano, 15(1), 387-395. https://doi.org/10.1021/acsnano.0c07392

Nanoscopic lamellae of centrosymmetric ferromagnetic alloys have recently been reported to host the biskyrmion spin texture; however, this has been disputed as the misidentication of topologically trivial type-II magnetic bubbles. Here we demonstrate... Read More about Tilted X-Ray Holography of Magnetic Bubbles in MnNiGa Lamellae.

Anisotropy-induced depinning in the Zn-substituted skyrmion host Cu2OSeO3 (2020)
Journal Article
Birch, M., Moody, S., Wilson, M., Crisanti, M., Bewley, O., Štefančič, A., Balakrishnan, G., Fan, R., Steadman, P., Alba Venero, D., Cubitt, R., & Hatton, P. (2020). Anisotropy-induced depinning in the Zn-substituted skyrmion host Cu2OSeO3. Physical review B - Condensed Matter and Materials Physics, 102(10), Article 104424. https://doi.org/10.1103/physrevb.102.104424

Magnetic skyrmions are nanosized topological spin textures stabilized by a delicate balance of magnetic energy terms. The chemical substitution of the underlying crystal structure of skyrmion-hosting materials offers a route to manipulate these energ...

Magnetic skyrmions are topologically nontrivial particles with a potential application as information elements in future spintronic device architectures. While they are commonly portrayed as two dimensional objects, in reality magnetic skyrmions are... Read More about Real-space imaging of confined magnetic skyrmion tubes.

Stability and metastability of skyrmions in thin lamellae of Cu2OSeO3 (2020)
Journal Article
Wilson, M., Birch, M., Štefančič, A., Twitchett-Harrison, A., Balakrishnan, G., Hicken, T., Fan, R., Steadman, P., & Hatton, P. (2020). Stability and metastability of skyrmions in thin lamellae of Cu2OSeO3. Physical Review Research, 2(1), Article 013096. https://doi.org/10.1103/physrevresearch.2.013096

We report small-angle x-ray scattering measurements of the skyrmion lattice in two 200-nm-thick Cu2OSeO3 lamellae aligned with the applied magnetic field parallel to the out of plane [110] or [100] crystallographic directions. Our measurements show t... Read More about Stability and metastability of skyrmions in thin lamellae of Cu2OSeO3.
