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…
Depth-dependent magnetic crossover in a room-temperature skyrmion-hosting multilayer
T. J. Hicken, M. N. Wilson, Z. Salman +8
Skyrmion-hosting multilayer stacks are promising avenues for applications, although little is known about the depth dependence of the magnetism. We address this by reporting the re…
Magnetism in the Néel skyrmion host GaVS under pressure
T. J. Hicken, M. N. Wilson, S. J. R. Holt +6
We present magnetization and muon-spin spectroscopy measurements of Néel skyrmion-host GaVS under the application of hydrostatic pressures up to GPa. Our results s…
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…
Experimental Evidence of a change of Exchange Anisotropy Sign with Temperature in Zn-Substituted Cu2OSeO3
S. H. Moody, P. Nielsen, M. N. Wilson +4
We report small-angle neutron scattering from the conical state in a single crystal of Zn-substituted Cu2OSeO3. Using a 3D vector-field magnet to reorient the conical wavevector, o…
Energy-gap driven low-temperature magnetic and transport properties in CrS ( = Nb or Ta)

The helimagnets CrS ( = Nb or Ta) have attracted renewed attention due to the discovery of a chiral soliton lattice (CSL) stabilized in an applied magnetic field, b…
Spin dynamics in bulk MnNiGa and MnPtPdSn investigated by muon spin relaxation
M. N. Wilson, T. J. Hicken, M. Gomilšek +7
We report muon spin relaxation and magnetometry studies of bulk MnPtPdSn and MnNiGa, two materials which have recently been proposed to host topological mag…
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…
SR study of triangular Ising antiferromagnet ErMgGaO
Y. Cai, C. Lygouras, G. Thomas +8
We present a detailed magnetic study of the triangular antiferromagnet ErMgGaO. A point charge calculation under the single ion approximation reveals a crystal field ground sta…

We present a muon spin relaxation study of the Mott transition in BaCoS_2 using two independent control parameters: (i) pressure p to tune the electronic bandwidth and (ii) Ni-subs…
Low-carrier density and fragile magnetism in a Kondo lattice system
Binod K. Rai, Iain W. H. Oswald, Wenjing Ban +17
Kondo-based semimetals and semiconductors are of extensive current interest as a viable platform for strongly correlated states. It is thus important to understand the routes towar…
