Studying Moire magnetism in 2D materials using diamond scanning probe

Moiré superlattices of twisted nonmagnetic two-dimensional (2D) materials are highly controllable

platforms for the engineering of exotic correlated and topological states. We studied intriguing 

magnetic textures in twisted 2D magnetic materials. Using single-spin

quantum magnetometry, we directly visualized nanoscale magnetic domains, and from it, calculated domain magnetization. We

observed unexpected magnetic domains with twisted angle dependence. We attribute the phenomenon to magnetic frustration which create a competition between different type of magnetic domains.
