Atomic scale skyrmions and large topological Hall effect in a breathing-kagome lattice

Nyayabanta Swain, Munir Shahzad, Pinaki Sengupta

Motivated by recent experiments in Gd${}_3$Ru${}_4$Al${}_{12}$, we demonstrate the emergence of atomic scale Skyrmions in interacting spins on a breathing kagome lattice with competing n…
