In this chapter, we summarize the whole thesis. Throughout the thesis, we have proposed the spin moiré picture to systematically discuss the control of the spin textures, their topological properties, and the emergent electromagnetic fields, and demonstrated these controls in a variety of topological spin textures in one, two, and three dimensions. Our results based on the spin moiré picture not only establish the versatile tool to study the control of topological magnetism but also pave the way for further exploration of topological spin textures and the resultant emergent electromagnetic phenomena.
