Detailed control of the spin degree of freedom promises new devices for electronics, quantum computing and neuromorphic computing. In recent years, moiré materials, such as twisted bilayer graphene, twisted multilayers of transition metal dichalcogenides or twisted graphene on hexagonal boron nitride, have emerged as a powerful platform to engineer correlated states. However, most correlated states are formed by achieving flat bands, with little control of the spin-degree of freedom. This mini-colloquium aims at bringing the spin control to the field of twisted van der Waals materials. Specifically, we aim to shed light on the complex interplay of spin-orbit interactions, exchange interactions, proximity effects induced by a substrate, light-induced excitations (such as Moiré excitons), superconducting pairing and topology. To achieve this goal, we will exchange theoretical insight and experimental progress on spin-control in moiré materials and bring together researchers from the fields of spintronics, spin-orbitronics and twistronics. It is our hope that this mini-colloquium will results in new avenue for engineering emergent states of twisted van der Waals heterostructures that will lead to exciting new physics as well as novel applications.
