Anisotropic skyrmion and multi- $q$ spin dynamics in centrosymmetric Gd $_{2}$ PdSi $_{3}$

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…

Controlling stable Bloch points with electric currents

Martin Lang, Swapneel Amit Pathak, Samuel J. R. Holt +2

The Bloch point is a point singularity in the magnetisation configuration, where the magnetisation vanishes. It can exist as an equilibrium configuration and plays an important rol…
