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.

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., …Hatton, P. (2020). Anisotropy-induced depinning in the Zn-substituted skyrmion host Cu2OSeO3. Physical review B, 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...

Real-space imaging of confined magnetic skyrmion tubes (2020)
Journal Article
Birch, M., Cortés-Ortuño, D., Turnbull, L., Wilson, M., Groß, F., Träger, N., …Hatton, P. (2020). Real-space imaging of confined magnetic skyrmion tubes. Nature Communications, 11, Article 1726. https://doi.org/10.1038/s41467-020-15474-8

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., …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.
