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 role in many magnetisation reversal processes. In the present work, we focus on manipulating Bloch points in a system that can host stable Bloch points-a two-layer FeGe nanostrip with opposite chirality of the two layers.

- The GaVSSe material family (y = 0 to 8) has been created in different forms and studied for their structural and magnetic characteristics, showing interesting properties at low temperatures.
- While the extreme materials GaVS and GaVSe transition to a different crystal structure at low temperatures, the intermediate compounds (y = 1 to 7) maintain their cubic symmetry even down to 1.5 K.
- The research suggests that the local spin arrangements in GaVS are influenced by charge ordering, and that the presence of structural and magnetic transitions is essential for the formation of skyrmion phases, which are not observed in the intermediate compounds due to their stable cubic structure.
