Confinement is an efficient approach to manipulate magnetic materials in order to stabilize complex states. In this work, the authors demonstrate its effect on a room-temperature van der Waals ferromagnet, Fe${}_{5}$GeTe${}_{2}$ using scanning NV center microscopy. They locally measure the magnetization in microstructures and reveal the presence of vortices as their ground state. The stray field images also highlight the effect of the size of the patterned structures on the stabilization of the vortices, in agreement with micromagnetic simulations, thus proposing a way to control noncollinear textures in van der Waals magnets.
