Pellet-Mary\n\nUniversity of Basel\n\n14h\, 9 Octobre 2025\n\nIJL\, Salle Patrick Alnot R+4 (N° 4-A014)\n\nENGINEERING ANTI-FERROMAGNETIC DOMAINS IN 2D CrSBr\n\nCrSBr is an emerging van der Waa ls magnet that has been gaining significant attention\, as it exfoliates e asily\n\ndown to the monolayer\, and remains stable under ambient conditio ns. It also supports a relatively high Curie\n\ntemperature of 140 K and e xhibits magneto-optical coupling through its excitons [1].\n\nA key challe nge in working with anti-ferromagnetic (AF) materials is the control and m easurement of their\n\norder parameter. In our work [2]\, we propose a nov el method to manipulate the AF order in a CrSBr bilayer\n\nby leveraging l ateral exchange interactions within a single crystalline flake.\n\nUsing s canning NV center magnetometry in a cryogenic environment [3]\, we were ab le to observe for the first\n\ntime the presence of AF domains in an atomi cally thin vdW magnet\, and to characterize the structural and\n\ntopologi cal properties of the resulting domain walls.\n\nFigure a : Schematics of the lateral exchange protocol used to create anti-ferromagnetic domains.\n \nb : Magnetic imaging of an anti-ferromagnetic domain wall in a CrSBr bil ayer.\n\nReferences\n\n[1] Ziebel\, M.
