Two-dimensional magnetic materials are a class of materials that exhibit magnetic properties down to their monolayer limit. These materials have garnered significant attention due to their potential applications in spintronics, data storage, and quantum computing.

Proximity effects in 2D van-der Waals semiconductor-magnetic heterostructures:
Valley manipulation in few-layer TMDs by means of an external magnetic field is of great research interest for applications, as well as for developing fundamental understanding, but such experiments require a very high magnetic field. Recently explored 2D heterostructures consisting of semiconducting & magnetic layers are promising platforms to study various magnetic proximity-induced phenomena like Zeeman splitting & valley polarization at much lower magnetic fields. We aim to explore & understand these phenomena in different combinations of TMDs & 2D magnetic materials.
