Two-dimensional (2D) materials have a rich category of material choice, with ultra-manipulable property and minimal interface intermixing in their heterostructures, which is ideal for spintronic devices. Even more exciting is the emerging superconductivity and magnetism in these moiré superlattices. The superconductivity may be unconventional, including the prospects of spin-triplet pairing. We probe and manipulate the spin properties by choosing different material combination and the alignment between the constituent materials of a heterostructure.
