Van der Waals materials are emerging as extremely versatile building blocks in many fields such as spintronics, superconductivity, nanoelectronics, optics, and may serve as tunable quantum simula-tors. These materials appear as extremely attractive for exploring new exotic physics due to their ability to be stacked with an infinite number of combinations that leads to unexpected physical properties. The recent discovery of ferromagnetism down to the monolayer limit in van der Waals materials confers new opportunities to engineer magnetic quantum materials. The family of chromium trihalide, CrCl3, CrBr3 and CrI3 (CrX3, X = I, Br, Cl) is one of the most promising classes of two-dimensional magnetic materials. Their integration in van der Waals heterostructure may give rises to the formation of moiré patterns which are expected to lead to a wealth of exotic ef-fects such as non-colinear magnetism. Indeed, we know from recent experimental and theoretical works that the moiré potential give rise to a periodic modulation of the magnetic interac-tion between neighboring atoms which can lead to the emergence of exotic non-collinear spin tex-ture such as spin spiral, vortex or skyrmion lattices.
