Incommensurate broken helix induced by nonstoichiometry in the axion insulator candidate EuInAs
Masaki Gen, Yukako Fujishiro, Kazuki Okigami +9
Zintl phase EuInAs has garnered growing attention as an axion insulator candidate, triggered by the identification of a commensurate double- broken-helix s…
Anisotropic skyrmion and multi- spin dynamics in centrosymmetric GdPdSi
M. Gomilšek, T. J. Hicken, M. N. Wilson +14
Skyrmions are particle-like vortices of magnetization with non-trivial topology, which are usually stabilized by Dzyaloshinskii-Moriya interactions (DMI) in noncentrosymmetric bulk…
Enhanced skyrmion metastability under applied strain in FeGe
M. T. Littlehales, L. A. Turnbull, M. N. Wilson +6
Mechanical straining of skyrmion hosting materials has previously demonstrated increased phase stability through the expansion of the skyrmion equilibrium pocket. Additionally, met…
X-ray holographic imaging of magnetic surface spirals in FeGe lamellae
L. A. Turnbull, M. T. Littlehales, M. N. Wilson +6
Isotropic helimagnets are known to host a diverse range of chiral magnetic states. In 2016, F.N. Rybakov et al. theorized the presence of a surface-pinned stacked spin spiral phase…
Bloch point-mediated skyrmion annihilation in three dimensions
M. T. Birch, D. Cortés-Ortuño, N. D. Khanh +5
The creation and annihilation of magnetic skyrmions are mediated by three dimensional topological defects known as Bloch points. Investigation of such dynamical processes is import…
Charge Density Waves and Coplanar Magnetism in Gd2PdSi3
S. H. Moody, M. N. Wilson, M. T. Birch +5
The intermetallic Gd2PdSi3 has recently generated a lot of excitement after reports that it hosts chiral magnetic nano-skyrmions despite its centrosymmetric crystal structure. Usin…
Pinning of Helimagnetic Phase Transitions in Zn-Substituted Skyrmion Host CuOSeO
M. T. Birch, S. H. Moody, M. N. Wilson +9
Magnetic skyrmions are nano-sized topological spin textures stabilized by a delicate balance of magnetic energy terms. The chemical substitution of the underlying crystal structure…
X-Ray Imaging of Mixed States of Skyrmions and Helices in FeGe
M. N. Wilson, L. A. Turnbull, F. Gross +8
We report scanning transmission X-ray microscopy of mixed helical and skyrmion magnetic states in thin FeGe lamellae. This imaging of the out-of-plane magnetism allows clear identi…
Real-space imaging of confined magnetic skyrmion tubes
M. T. Birch, D. Cortés-Ortuño, L. A. Turnbull +20
Magnetic skyrmions are topologically nontrivial particles with a potential application as information elements in future spintronic device architectures. While they are commonly po…
Stability and Metastability of Skyrmions in Thin Lamellae of CuOSeO
M. N. Wilson, M. T. Birch, A. Štefančič +6
We report small angle X-ray scattering (SAXS) measurements of the skyrmion lattice in two 200~nm thick CuOSeO lamellae aligned with the applied magnetic field parallel to t…
Measuring the Formation Energy Barrier of Skyrmions in Zinc Substituted CuOSeO
M. N. Wilson, M. Crisanti, C. Barker +6
We report small angle neutron scattering (SANS) measurements of the skyrmion lattice in (CuZn)OSeO under the application of an electric field. These mea…
Local magnetism, magnetic order and spin freezing in the 'nonmetallic metal' FeCrAs
B. M. Huddart, M. T. Birch, F. L. Pratt +7
We present the results of x-ray scattering and muon-spin relaxation (SR) measurements on the iron-pnictide compound FeCrAs. Polarized non-resonant magnetic x-ray scattering…
Increased lifetime of metastable skyrmions by doping
M. T. Birch, R. Takagi, S. Seki +12
Previous observations of metastable magnetic skyrmions have shown that close to the equilibrium pocket the metastable state has a short lifetime, and therefore rapid cooling is req…
Origin of skyrmion lattice phase splitting in Zn-substituted CuOSeO
A. Štefančič, S. Moody, T. J. Hicken +15
We present an investigation into the structural and magnetic properties of Zn-substituted CuOSeO, a system in which the skyrmion lattice (SkL) phase in the magnetic fie…
