Room-Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Summary

This study demonstrates a room-temperature skyrmionic synapse in Fe3GaTe2 based on collective spin texture transformation.

My contribution

I led the theoretical validation using GPU-accelerated micromagnetic simulations, reproduced the observed skyrmion-to-stripe transformation, and clarified the thermodynamic relaxation mechanism assisted by spin-orbit torque. I also quantified topological charge annihilation to distinguish domain drift from true phase transition.
