Summary

This paper reports thermodynamic and structural signatures of ferrimagnetism in Fe3GaTe2 and connects local symmetry breaking to emergent chiral textures.

My contribution

I investigated how local symmetry breaking affects topological textures and differentiated between Neel and Bloch-hybrid skyrmion types by tuning material parameters to match Lorentz TEM observations.
