Antiferromagnetic skyrmions have been theoreticallyproposed to be a 2D object of research interest. Not only should it betopologically protected and could be potentially used as a fundamental blockfor future spintronic devices, it also benefits from the anti-alignment ofspins in antiferromagnets so that it could move straight and faster thanferromagnetic counterparts. In the LNO groups of CEA SPEC, Zixin studies themodelling of BiFeO3 (BFO). He developed a program to simulate spin dynamicswith GPU acceleration and uses it to study the antiferomagnetic skyrmionin BFO.
