Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions
Advanced Materials, EarlyView.ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.
