Spectroscopy and Synthesis of 2D Magnetic Materials<\/h3>\t\t\t

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.<\/p>\n

Proximity effects in 2D van-der Waals semiconductor-magnetic heterostructures:<\/strong>
\nValley 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.<\/p>\n

Synthesis of wafer-scale 2D magnetic crystals:<\/strong>
\nA key challenge for 2D magnets is scalable, high-quality synthesis. Using a tailored vapour deposition approach, we have demonstrated large-grain, wafer-scale epitaxial growth of CrCl\u2083 \u2014 a layered van der Waals antiferromagnet. By employing several synthesis innovations, we achieve single-crystal grains far exceeding those from conventional CVD. This opens a route to integrating 2D magnetic materials into scalable spintronic and quantum devices.<\/p>\n
