The moiré superlattice in magnetic two-dimensional (2D) materials has revealed intriguing correlated and topological states. In the second part, we employ the scanning NV probe technique to investigate the antiferromagnetic domain of twisted double bilayer CrI3. Our study has shown that the magnetic competition in the moiré superlattice can contribute to the spontaneous periodic magnetic order in the twisted antiferromagnets. Notably, our observations include periodic antiferromagnetic texture with a period significantly larger than the moiré period and the emergence of the *skyrmion-like* lattices after a field cooldown process.
